CQ1

CQ1boards are 4-port channelized STM-1 processing boards.
Functions
1- Receives and transmits four channels of channelized STM-1 optical/ electrical signals.
2- Supportespacketservice types and Circuit emulation service (CES) E1 l ML-PPP E1.
3- Supporters  Optical ports l Uses small form-factor pluggable (SFP) optical modules to provide optical ports of the Ie-1, S-1.1, L-1.1, and L-1.2 types. And Complies with ITU-T G.957.
4- Electrical ports l Uses SFP electrical modules. And Complies with ITU-T G.703.
5- OutbandDCN Each SDH line port can provide one data communications channel (DCC) that is composed of three DCC bytes, nine DCC bytes, or 12 DCC bytes.
6- InbandDCN Transmits DCN information over ML-PPP links.
7- Loopback Supports inloops at STM-1 ports. l Supports outloopsat STM-1 ports. l Supports inloopsover E1 channels. l Supports outloopsover E1 channels.
