V1.0: Class 1 fax — real-world 4-page send to external number confirmed

Browse Source 
Core features:
- Class 1 T.30 protocol: full send/receive implementation
- HDLC: DLE-stuffing, FCS strip, USR5637 bit-reversal handling
- T.4 MH encoder/decoder (1728px A4 standard)
- Document pipeline: PDF (Ghostscript), PNG, TIFF input
- Width clamping: US Letter 1734px → 1728px fax standard
- Cover page: CJK rasterization (TW/CN/JP/EN), TIFF + HTML output
- OCR verification: Tesseract 5 with eng+chi_tra, CJK space-tolerant
- API server (axum): health, send, jobs, cover, retry, cancel
- Background worker: auto-poll queue, speed fallback, retry policy
- Modem detection, pool management

Real-world test results (2026-07-23):
- V90 → 25153038: 4 pages, V.17 12000 bps, 2:33 ✅
- USR5637 → 25153038: 4 pages, V.17 12000 bps, 2:26 ✅
- Both faxes confirmed received on remote machine

Tested: loopback (100% pixel match), multi-page, all input formats,
cover pages, OCR verify, API endpoints, worker processing.
13 unit tests pass, 0 new clippy warnings.

## Worker Configuration
The background worker processes jobs from the queue:
- **Poll Interval**: 5 seconds (checks for pending jobs)
- **Retry Policy**: 3 retries with exponential backoff (1min, 5min, 15min)
- **Speed Fallback**: On training failure, lowers speed: 14400 → 12000 → 9600 → 7200 → 4800
- **Concurrent Jobs**: 1 per modem (configurable)
## Monitoring
### Health Check Endpoint
```
GET /api/health
```
### Prometheus Metrics
```
GET /api/metrics
```
### Logging
All logs go to systemd journal with structured fields:
- `job_id`: Current job being processed
- `modem_name`: Modem in use
- `status`: Operation status

# Telfax Class 1 Fax Design Document
## Overview

└── executor.rs — Background job processor (queue → modem)
```
## Class 1 Protocol Implementation
### T.30 State Machine
Class 1 offloads HDLC framing and modulation to the host software. The modem acts as a raw data pump.
#### Sender (send.rs)
```
Dial → Wait CONNECT → Escape → FRH (receive DIS)
→ Parse DIS capabilities → Build DCS
→ FTH=3 (send DCS) → FTM=n (send TCF)
→ FRH (receive CFR/FTT)
→ [For each page]:
FTM=n (send page data) → FTH=3 (send MPS/EOP)
→ FRH (receive MCF)
→ FTH=3 (send DCN) → Hangup
```
#### Receiver (recv.rs)
```
ATA → Wait RING → Answer → Wait DIS/DCS
→ FRM=n (receive page data) → FTH=3 (send MCF)
→ [For each page]:
FRH (receive MPS/EOP/DCN)
→ FTH=3 (send MCF if more pages)
→ Hangup
```
### HDLC Layer (hdlc.rs)
The modem strips HDLC flags and bit-stuffing on FRH=3. We handle:
1. **DLE-stuffing**: Per T.31, 0x10 → 0x10 0x10. `dle_unstuff()` reverses this.
2. **FCS stripping**: USR5637 outputs the 2-byte CRC-CCITT as part of frame data. `parse_modem_hdlc()` strips it.
3. **Bit reversal**: USR5637 reverses ALL bytes during FTH=3 transmission. The receiver must reverse them back to get correct frame content. `parse_modem_hdlc()` applies `reverse_bits()` to all bytes.
4. **FCF masking**: Bit 7 of the FCF byte is an address extension bit set by the calling station. `parse_modem_hdlc()` masks it with `0x7F`.
### Bit Reversal Details
USR5637 modem reverses bit order (MSB↔LSB) on **every byte** during FTH=3. This is not documented in the modem manual but was discovered during testing.
```
Original: 0xFF → 0xFF (all ones, no change)
0x01 → 0x80
0x03 → 0xC0
0x28 → 0x14
```
The `reverse_bits()` function pre-reverses bytes before FTH=3 transmission. On FRH=3 receive, the modem does NOT reverse, so received data is already in correct orientation — but the *sender's* FTH=3 reversal must be undone by the parser.
### T.4 Page Data
#### Encoding (send)
1. Grayscale pixels → threshold to B&W (128/255 threshold)
2. Each scan line → MH run-length encoding via `MhEncoder`
3. MH-encoded bytes → DLE-stuff → transmit via FTM=n
#### Decoding (recv)
1. Raw bytes from FRM=n → DLE-unstuff
2. MH bitstream → run-length decode → pixel array
3. `find_first_eol_bit()` locates the EOL marker (11+0...01 pattern)
4. `transitions_to_pixels()` converts alternating run lengths to pixel data
### Data Rates
| Modulation | FRM/FTM value | Speed | Use |
|---|---|---|---|
| V.21 (300 baud) | 3 | HDLC signaling | DIS/DCS/MCF/etc. |
| V.27ter (4800) | 5 | Page data (low) | Fallback |
| V.27ter (9600) | 6 | Page data (default) | Standard |
| V.29 (9600) | 7 | Page data | Alternate |
| V.29 (14400) | 8 | Page data (fast) | High speed |
| V.17 (12000) | 145 | Training (TCF) | Negotiation |
| V.17 (12000) | 146 | Page data | Fastest stable |
### FCS Computation
CRC-CCITT polynomial: x^16 + x^12 + x^5 + 1 (0x1021)
- Initial value: 0xFFFF
- Reflected input/output
- Final XOR: 0xFFFF
- FCS = complement of CRC
## Modem Compatibility
### Tested Modems
| Modem | Class 1 | Class 2 | Notes |
|---|---|---|---|
| USR5637 | ✅ | ✅ | Bit reversal on FTH=3. FCS not stripped. Reliable. |
| V90 CX93001 | ✅ | ❌ | Class 2 FDT returns OK but internal T.30 fails (FHNG:025). Use Class 1. |
### Modem Detection
```bash
AT+GMI → Manufacturer
AT+GMM → Model
ATI3 → Model (fallback)
AT+FCLASS=? → Class support
AT+FTM=? → TX rate capabilities
AT+FRM=? → RX rate capabilities
```
## Document Pipeline
### Input Formats
| Format | Path | Conversion |
|---|---|---|
| TIFF (existing) | Direct | Parse pages, use as-is |
| PDF | pdf.rs | Ghostscript → TIFF-G3 → pixel extraction |
| PNG/JPEG | convert.rs | image crate → grayscale → threshold → width clamp |
### Width Handling
Standard fax width: **1728 pixels** (A4 at 204 DPI).
- PDFs at US Letter (8.5") → 1734px at 204 DPI → clamped to 1728 via `width.min(1728)`
- Images wider than 1728 → scaled down proportionally
- Images narrower than 1728 → no scaling
### Cover Pages
Generated via `cover.rs`:
- Rasterizes text to grayscale bitmap using PingFang CJK font
- Supports Traditional Chinese, Simplified Chinese, Japanese, English
- Output: 1728×2291 pixels (standard fax page)
- Formats: TIFF (for fax) or HTML (for preview)
### OCR Verification
`verify-cover` command:
1. Generate cover page TIFF
2. Run Tesseract OCR (eng + chi_tra) with PSM 3
3. Strip whitespace from OCR output (CJK characters get spaces inserted)
4. Compare fields: FACSIMILE, TO, FROM, DATE, PAGES, SUBJECT, NOTES
## API Server
### Endpoints
| Method | Path | Description |
|---|---|---|
| GET | /api/health | Server health + modem status |
| POST | /api/fax/send | Queue a fax job |
| GET | /api/fax/jobs | List all jobs |
| GET | /api/fax/jobs/{id} | Get job details |
| PUT | /api/fax/jobs/{id}/cover | Update cover page fields |
| POST | /api/fax/jobs/{id}/retry | Retry a failed job |
| DELETE | /api/fax/jobs/{id} | Cancel a job |
### Worker
Background `FaxWorker` polls the queue every 5 seconds:
1. Dequeue pending job
2. Load document (PDF/TIFF/image)
3. Prepend cover page if cover fields present
4. Open modem, negotiate, transmit
5. Handle retries with speed fallback (V.17 → V.29 → V.27ter)
## Key Design Decisions
1. **Class 1 over Class 2**: Class 1 gives full control over T.30 protocol. Class 2 depends on modem firmware which varies wildly (V90 Class 2 is broken).
2. **Pre-reverse bytes for FTH=3**: Instead of relying on modem firmware, we pre-reverse all bytes before FTH=3 to compensate for USR5637's undocumented bit reversal.
3. **Split parser**: `parse_hdlc_payload()` (clean) vs `parse_modem_hdlc()` (modem-specific with FCS strip + bit reversal). Tests use the clean parser; production code uses the modem parser.
4. **Width clamping at 1728**: Rather than failing on slightly wider documents, clamp to standard fax width. Minor clipping at edges is acceptable.
5. **MH encoding always**: Even though TIFF-G3 supports MR and MMR, we use MH (Group 3) for maximum compatibility with all receiving fax machines.
## Test Hardware

# Telfax 生產環境部署指南
## 系統需求
- macOS 10.14 或更新版本
- USB 數據機（已測試：V90, USR5637）
- 已安裝 Rust 工具鏈（用於編譯）
- 管理員權限（用於安裝服務）
---
## 快速部署（V90 Class 2）
### 1. 編譯發布版本
```bash
cd /path/to/telfax
cargo build --release
```
### 2. 安裝服務
```bash
sudo ./deployment/install-macos.sh
```
### 3. 配置服務
編輯配置文件：
```bash
nano /usr/local/etc/telfax/config.toml
```
**重要配置項：**
```toml
# 認證令牌（必須修改！）
[[auth.tokens]]
token = "your-secure-token-here" # 修改為安全令牌
permissions = "admin"
# V90 數據機（Class 2 生產環境）
[[modems]]
device = "/dev/cu.usbmodem123456781" # 確認設備路徑
name = "V90-Primary"
class = 2 # 使用 Class 2（穩定）
priority = 1
enabled = true
phone_number = "25289852" # 設定電話號碼
# 傳真設定
[fax]
station_id = "+886-2-25289852" # 設定傳真號碼
header = "Your Company Name" # 設定公司名稱
default_class = 2 # 預設使用 Class 2
```
### 4. 啟動服務
```bash
# 載入服務
sudo launchctl load -w /Library/LaunchDaemons/com.telfax.server.plist
# 檢查狀態
sudo launchctl list | grep telfax
# 查看日誌
tail -f /usr/local/var/log/telfax/telfax.log
```
### 5. 測試 API
```bash
# 健康檢查
curl http://localhost:3000/health
# 查看狀態（需要認證）
curl -H "Authorization: Bearer your-secure-token-here" \
http://localhost:3000/api/v1/status
# 查看數據機狀態
curl -H "Authorization: Bearer your-secure-token-here" \
http://localhost:3000/api/v1/modems
# 查看 Prometheus 指標
curl http://localhost:9090/metrics
```
---
## 發送傳真測試
### 準備測試文件
```bash
# 創建測試封面頁
cat > test_cover.json <<EOF
{
"to_name": "測試接收方",
"to_number": "25153038",
"from_name": "Telfax 測試",
"subject": "傳真測試",
"message": "這是一封測試傳真"
}
EOF
```
### 發送傳真
```bash
# 發送傳真
curl -X POST http://localhost:3000/api/v1/fax/send \
-H "Authorization: Bearer your-secure-token-here" \
-H "Content-Type: application/json" \
-d @test_cover.json
```
### 查看任務狀態
```bash
# 列出所有任務
curl -H "Authorization: Bearer your-secure-token-here" \
http://localhost:3000/api/v1/jobs
# 查看特定任務
curl -H "Authorization: Bearer your-secure-token-here" \
http://localhost:3000/api/v1/jobs/{job_id}
```
---
## 接收傳真測試
### 檢查接收功能
1. 確保數據機已連接並啟用
2. 服務會自動接聽來電
3. 接收的傳真會存儲在 `/usr/local/var/lib/telfax/received/`
```bash
# 查看接收的傳真
ls -lh /usr/local/var/lib/telfax/received/
# 查看接收歷史
curl -H "Authorization: Bearer your-secure-token-here" \
http://localhost:3000/api/v1/fax/received
```
---
## 監控與維護
### 日誌查看
```bash
# 即時日誌
tail -f /usr/local/var/log/telfax/telfax.log
# 錯誤日誌
tail -f /usr/local/var/log/telfax/telfax-error.log
# macOS 系統日誌
log show --predicate 'process == "telfax"' --last 1h
```
### Prometheus 監控
```bash
# 查看指標
curl http://localhost:9090/metrics
# 關鍵指標
# - telfax_fax_sent_total
# - telfax_fax_received_total
# - telfax_fax_failed_total
# - telfax_modem_status
# - telfax_job_queue_size
```
### 服務管理
```bash
# 停止服務
sudo launchctl unload /Library/LaunchDaemons/com.telfax.server.plist
# 重啟服務
sudo launchctl unload /Library/LaunchDaemons/com.telfax.server.plist
sudo launchctl load -w /Library/LaunchDaemons/com.telfax.server.plist
# 檢查服務狀態
sudo launchctl list | grep telfax
```
---
## 故障排除
### 數據機無法連接
```bash
# 檢查設備路徑
ls -l /dev/cu.usbmodem*
# 檢查權限
ls -l /dev/cu.usbmodem123456781
# 測試連接
screen /dev/cu.usbmodem123456781 115200
# 輸入: ATI
# 應返回數據機信息
```
### 服務無法啟動
```bash
# 檢查配置文件
/usr/local/bin/telfax serve --config /usr/local/etc/telfax/config.toml
# 檢查權限

✅ 无需额外安装
```
**实施：**
```rust
// src/ocr/mod.rs
impl OcrProcessor {
pub fn new_optimized() -> Self {
Self {
config: OcrConfig {
// 使用 LSTM 神经网络引擎（最准确）
oem: OcrEngineMode::NeuralNetLstmOnly,
// 自动页面分割（最灵活）
psm: PageSegMode::Auto,
// 高DPI传真图像
dpi: 204, // 或更高: 300
// 多语言组合
language: OcrLanguage::Multi(vec!["chi_tra", "eng"]),
},
}
}
pub fn process_with_optimization(&self, image_path: &Path) -> Result<OcrResult> {
let mut args = vec![
image_path.to_string_lossy().to_string(),
"stdout".to_string(),
// 最佳参数
"-l".to_string(), self.get_best_language_combo(),
"--dpi".to_string(), "204".to_string(),
"--oem".to_string(), "1".to_string(), // LSTM only
"--psm".to_string(), "3".to_string(), // Auto
// 高级参数
"--dpi".to_string(), "300".to_string(), // 提高DPI
"quiet".to_string(),
];
// 添加语言特定配置
args.push("-c".to_string());
args.push("tessedit_char_whitelist=0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz".to_string());
// 执行OCR
let output = Command::new(&self.tesseract_path)
.args(&args)
.output()?;
Ok(self.parse_result(output))
}
fn get_best_language_combo(&self) -> String {
match &self.config.language {
OcrLanguage::ChineseTraditional => "chi_tra_best+eng",
OcrLanguage::ChineseSimplified => "chi_sim_best+eng",
OcrLanguage::Japanese => "jpn_best+eng",
_ => "eng",
}

-l chi_tra_best # 最佳语言包
```
**效果预估：**
```
Chinese: +5-10% accuracy
Free: Yes
Time: +50ms
```
---
### 方案 4: 字体优化（核心）⭐⭐⭐⭐⭐
**问题根源：**
```
中文OCR准确度低的原因：
1. 测试图片使用Helvetica字体（不支持中文）
2. PIL默认字体不支持中文字符
3. 需要使用专门的中文字体
```
**解决方案：**
```python
# scripts/cover_multilang.py
def create_chinese_cover_with_font(text, output_path):
from PIL import Image, ImageDraw, ImageFont
W, H = 1728, 2291
img = Image.new('L', (W, H), 255)
draw = ImageDraw.Draw(img)
# 使用中文字体（关键）
CHINESE_FONT_PATHS = [
'/System/Library/AssetsV2/com_apple_MobileAsset_Font8/86ba2c91f017a3749571a82f2c6d890ac7ffb2fb.asset/AssetData/PingFang.ttc',
'/System/Library/Fonts/STHeiti Medium.ttc',
'/usr/share/fonts/truetype/wqy/wqy-zenhei.ttc', # Linux
'/usr/share/fonts/opentype/noto/NotoSansCJK-Regular.ttc', # Linux
]
font_path = None
for path in CHINESE_FONT_PATHS:
if os.path.exists(path):
font_path = path
break
if font_path:
if 'PingFang' in font_path:
# PingFang字体索引（关键）
font_title = ImageFont.truetype(font_path, 72, index=10) # TC-Semibold
font_bold = ImageFont.truetype(font_path, 44, index=6) # TC-Medium
font_normal = ImageFont.truetype(font_path, 44, index=2) # TC-Light
else:
font_title = ImageFont.truetype(font_path, 72)
font_bold = ImageFont.truetype(font_path, 44)
font_normal = ImageFont.truetype(font_path, 44)
else:
# 下载并安装字体（可选）
print("Warning: No Chinese font found. Downloading...")
# 可以在这里添加自动下载逻辑
# 绘制中文文本
lines = text.split('\n')
y = 100
for line in lines:
draw.text((100, y), line, fill=0, font=font_normal)
y += 60
img.save(output_path, dpi=(204, 196))
```
**效果预估：**
```
Chinese OCR: 60% → 90%+ (字体匹配)
Key insight: OCR准确度取决于字体匹配度
```
---
### 方案 5: 多次OCR + 结果融合（高准确度）⭐⭐⭐
**原理：**
```
多次OCR处理不同参数，融合结果：
1. English only OCR
2. Chinese only OCR
3. Combined OCR
4. 选择最佳结果
```
**实施：**
```rust
pub fn multi_pass_ocr(&self, image_path: &Path) -> Result<OcrResult> {
let mut results = Vec::new();
// Pass 1: English only
let eng_result = self.process_with_language(image_path, "eng")?;
results.push(eng_result);
// Pass 2: Chinese Traditional
let chi_result = self.process_with_language(image_path, "chi_tra")?;
results.push(chi_result);
// Pass 3: Combined
let combined_result = self.process_with_language(image_path, "chi_tra+eng")?;
results.push(combined_result);
// 选择最佳结果（最高置信度）
let best_result = results.iter()
.max_by_key(|r| r.word_count)
.unwrap();
Ok(best_result.clone())
}
```
**效果预估：**
```
Accuracy: +10%
Processing: +300ms (3次处理)
Quality: High
```
---
### 方案 6: 机器学习后处理（高级）⭐⭐⭐
**原理：**
```
使用机器学习纠正OCR错误：
1. 收集常见错误样本
2. 训练纠错模型
3. 应用到OCR结果
```
**实施：**
```rust
// src/ocr/postprocess.rs
pub struct OcrPostProcessor {
// 常见错误纠正表
error_correction_map: HashMap<String, String>,
}
impl OcrPostProcessor {
pub fn correct_ocr_text(&self, text: &str) -> String {
let mut corrected = text.clone();
// 常见OCR错误纠正
let corrections = vec![
("O", "0"), // 数字0识别为字母O
("l", "1"), // 数字1识别为字母l
("S", "5"), // 数字5识别为字母S
("B", "8"), // 数字8识别为字母B
];
for (wrong, correct) in corrections {
// 根据上下文判断是否应该纠正
corrected = self.smart_replace(&corrected, wrong, correct);
}
corrected
}
fn smart_replace(&self, text: &str, wrong: &str, correct: &str) -> String {
// 智能替换：只在数字上下文中替换
// 例如：电话号码中的O→0，但单词中的O保留
let mut result = text.clone();
for (i, c) in text.char_indices() {
if c.to_string() == wrong {
// 检查周围字符是否是数字
let prev = text.chars().nth(i-1);
let next = text.chars().nth(i+1);
if prev.map(|p| p.is_digit(10)).unwrap_or(false) ||
next.map(|n| n.is_digit(10)).unwrap_or(false) {
result.replace_range(i..i+1, correct);
}
}
}
result
}
}
```
**效果预估：**
```
Accuracy: +5-8%
Processing: +20ms
Complexity: Medium
```

## Rust OCR 替代方案
### 1. Rust Tesseract Wrapper
**tesseract-rs:**
```rust
// Rust wrapper for Tesseract C++
use tesseract::Tesseract;
let mut tess = Tesseract::new();
tess.set_language("eng");
tess.set_image("image.png");
let text = tess.get_text();
```
**项目：**
- https://github.com/antrew/tesseract-rs
- Rust wrapper around C++ Tesseract
- Uses unsafe FFI
---
### 2. Pure Rust OCR Engines
#### A. **leptess**
```rust
use leptess::LepTess;
let mut lt = LepTess::new(Some("eng"), "image.png")?;
let text = lt.get_text()?;
```
**特点：**
- Rust wrapper for Leptonica + Tesseract
- Type-safe bindings
- Memory-safe interface
#### B. **ocropy-rs**
```rust
// Python OCRopy port to Rust
// Experimental project
```
**状态：**
- 实验性项目
- 功能有限
#### C. **cuneiFORM-rs**
```rust
// Rust port of cuneiFORM OCR
// Historical document OCR
```
**状态：**
- 开发中

// Call Tesseract C++ via subprocess
let output = Command::new(&self.tesseract_path)
.arg(image_path)
.arg("stdout")
.output()?;
// Parse results in Rust

# Telfax Web UI
Modern Web UI for Telfax Enterprise Fax Server built with **Tauri + Vue 3 + TypeScript**.
## Features
- **Dashboard**: Real-time status overview, send faxes directly
- **Fax History**: View and manage fax jobs
- **Modem Status**: Monitor modem health and status
- **Settings**: Configure API connection and authentication
## Tech Stack
- **Frontend**: Vue 3 + TypeScript + Vite
- **Styling**: Tailwind CSS
- **State Management**: Pinia
- **Routing**: Vue Router 4
- **HTTP Client**: Axios
- **Desktop App**: Tauri 2.0
## Development
### Prerequisites
- Node.js 18+
- Rust (for Tauri)
- Telfax backend running on `http://localhost:3000`
### Install Dependencies
```bash
cd web-ui
npm install
```
### Run Development Server
```bash
# Web only (for development)
npm run dev
# Desktop app (with Tauri)
npm run tauri dev
```
The app will be available at `http://localhost:1420`
### Build for Production
```bash
# Build web app
npm run build
# Build desktop app (all platforms)
npm run tauri build
```
## Configuration
### Environment Variables
Create `.env` file in `web-ui/` directory:
```env
VITE_API_URL=http://localhost:3000
VITE_API_TOKEN=your-api-token-here
```
### Production Configuration
1. Set API URL in `.env`:
```env
VITE_API_URL=https://your-server.com
VITE_API_TOKEN=prod-admin-token-change-me-abc123xyz
```
2. Build and deploy:
```bash
npm run build
```
3. Deploy `dist/` directory to your web server

```
## API Endpoints
The Web UI connects to the Telfax backend REST API:
| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/v1/status` | GET | Server status |
| `/api/v1/modems` | GET | List modems |
| `/api/v1/jobs` | GET | List fax jobs |
| `/api/v1/jobs/:id` | GET | Get job details |
| `/api/v1/fax/send` | POST | Send fax |
| `/api/v1/jobs/:id/cancel` | POST | Cancel job |
All endpoints require `Authorization: Bearer <token>` header.
## Screenshots
### Dashboard
- Real-time statistics (total, pending, completed, failed jobs)
- Quick send fax form
- Active modems overview
### Fax History
- Table view of all fax jobs
- Status badges
- Cancel pending jobs
### Modem Status
- Modem health monitoring
- Class and priority information
- Status indicators (idle, busy, error, disabled)
### Settings
- API URL configuration
- Authentication token management
- App information
## Desktop App Features
When running as a Tauri desktop app:
- Native window controls
- System tray integration (optional)
- Auto-update support (optional)
- Offline mode (view cached data)
- Native notifications
## Troubleshooting
### Development Issues
1. **API Connection Failed**
- Check if Telfax backend is running
- Verify `.env` configuration
- Check CORS settings on backend
2. **Build Errors**
- Run `npm install` to ensure dependencies
- Check Node.js version (18+)
- Clear cache: `rm -rf node_modules package-lock.json && npm install`
3. **Tauri Build Fails**
- Ensure Rust is installed
- Check platform-specific dependencies
- Run `npm run tauri dev` first to test
### Production Issues
1. **Authentication Errors**
- Verify API token in Settings
- Check token permissions (admin/write/read)
2. **Modem Not Detected**
- Check backend logs
- Verify modem device paths in backend config
