Interface cable

The MIM-1CE3 provides two SMB interfaces, with one interface acting as the transmission end (Tx) and

the other as the receiving end (Rx). The Tx and Rx interfaces operate in the 75-ohm unbalanced

transmission mode and thereby need a pair of 75-ohm unbalanced coaxial cables in use for connection

with the peer device.

NOTE:

• The MIM-1CT3 and MIM-1CE3 use the same type of E3/T3 cable.

• The E3/T3 cable is an optional accessory for the MIM-1CE3 to be separately ordered if needed.

• For the appearance and connection of an E3/T3 cable, see Connecting a CE3/CT3 inter

face cable.

MIM-1ATM-OC3

The MIM-1ATM-OC3 is a 1-port 155 Mbps ATM optical interface module.

An ATM interface module provides an ATM interface for the device. It has the following features:

• Supports two frame formats, SDH STM-1 and SONET OC-3.

• Supports scrambling transmission.

• Adopts two clock modes: line clock (when the interface on it is used as a DTE interface) and internal

clock (when the interface on it is used as a DCE interface).

• Supports three types of loopback testing: local cell loopback, local payload loopback, and remote

loopback.

For more information about ATM interfaces, see HP 6600/HSR6600 Routers Interface Configuration

Guide or HP HSR6800 Routers Interface Configuration Guide.
