SRP IOA

Module label SRP IOA

IOA label

Not applicable

Number of IOA ports

3

Software release

First supported: 7.0.1

Description

10 W

Pairs with SRP module

Interfaces with the SRP modules through the system's midplane.

Capability

Ethernet (IEEE 802.3)

10/100Base-T

RS-232

Auxiliary port allows access to debug ports on a specific processor (SRP module, LM).

External clock input accepts T1 or E1 signaling. You must configure the interface for T1 or E1. No additional configuration for a specific framing mode is required (for example, SF/ESF).

The BNC connector has a 75–Ohm load impedance.

T1 inputs must be converted from a balanced 100–Ohm signal to an unbalanced 75–Ohm signal by using a balun.

The minimum signal amplitude at the BNC connector is 400mV peak.
