PA-4T+ Cisco - Expansion module

Device Type

Expansion module - 4 ports

Interfaces

4 x serial - RS-530/RS-449/RS-232/V.35/X.21 - 60 pin D-Sub (DB-60) - 4

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

Cabling Type

Serial

Data Transfer Rate

2 Mbps
