Cisco PA-4T+
4 Port Serial Port Adapter, Enhanced
Product Highlights
Increasing demand for bandwidth-intensive services and wide-area network (WAN) connectivity requires that network administrators maximize the capacity and efficiency of network routers. Cisco Systems' four-port serial port adapter provides network administrators with flexible options for a broad range of port density requirements. Cisco's four-port serial port adapter enhances network performance at a low price per port---making them the most cost-effective solution for maximizing router efficiency.
The four-port adapter (PA-4T+) provides four synchronous serial ports. Each port supports full-duplex operations at T1 and E1 speeds. A single port can support up to E2 speeds.
Each port also supports a variety of interface types, determined by the separately purchased cable type connected to it. Supported interfaces include EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530, allowing flexible deployments as either DCE or DTE equipment. The four-port adapter is the most cost-effective solution for low-traffic WAN connections or remote Cisco 7200 installations.

System Requirements
- The PA-4T+ port adapter requires only a single slot in a Cisco 7200 Series router
- For Cisco 7500 Series routers, it requires one of the two available adapter slots on a Versatile Interface Processor (VIP2)
- Requires IOS Release 11.1.8CA (and above) or 11.2.5P (and above)
Additional Information
- When two full-duplex ports are in use, the maximum speed for each is 4 Mbps
- When four full-duplex ports are in use, the maximum speed for each is 1.55 Mbps (T1) or 2.048 Mbps (E1) Network interfaces:
- Four full-duplex ports at T1 (1.55 Mbps) or E1 (2.048 Mbps)
- Two full-duplex ports at up to 4 Mbps each
- One full-duplex port at up to E2 speeds (8 Mbps)
- Electrical interfaces (selectable via cable selection) - V.35 - EIA/TIA-232 - EIA/TIA-449 - EIA-530 - X.21 Four-port design provides flexibility:
- Supports four full-duplex T1/E1 connections or a single full-duplex E2 connection
- All ports use identical 60-pin, D-shell receptacle that supports all interface types (i.e. RS232, RS449, RS530, V.35, x.21)
- Adapter cables determine the electrical interface and port mode data terminal equipment (DTE) or data communications equipment (DCE) Carrier-Class Reliability and Serviceability:
- Field-replaceable design permits online insertion and removal for continuous router availability
- Port adapter handles simplify installation and removal
- Support for loopback for remote diagnostics
- LEDs indicate when the adapter is enabled for operation
- Separate LEDs for each port indicate DTE or DCE function, transmit data, transmit clock, receive data, and receive clock signals
- Metric (M3) thumbscrews included with each port adapter cable allow connections to devices that use metric hardware
