Channelized MDA/CMA Support

Channelized MDA/CMA Support

Channelized DS-1/E-1 CMA

Each 8-port channelized DS-1/E-1 CMA supports channelization down to DS-0. Each 8-port
channelized DS-1/E-1 CMA supports 64 channel groups. This CMA is not supported on the 7450-
ESS.

Channelized DS-3/E-3 MDA

Each 4-port or 12-port channelized DS-3/E-3 media dependent adapter (MDA) supports
channelization down to digital signal level 0 (DS-0) using a maximum of 8 or 24 (respectively)
1.0/2.3 coaxial connectors. Each port consists of one receive (RX) coaxial connector and one
transmit (TX) coaxial connector.
Each physical DS-3 connection can support a full clear-channel DS-3, or it can be channelized into
independent DS-1/E-1 data channels. Each DS1/E1 channel can then be further channelized down
to DS-0s. E-3 ports do not support channelization. They only support clear channel operation.
Each DS-3/E-3 MDA supports 512 channels with DS-0 timeslots that are used in the DS-1/E-1
channel-group.
This MDA is not supported on the 7450-ESS.

Channelized CHOC-12/STM-4 MDA

Each 1-port channelized OC-12/STM-4 MDA supports channelization down to DS-0 and accepts
one OC-12/STM-4 SFP small form factor pluggable (SFP) module. The same SFP optics used on
Alcatel-Lucent's SONET/SDH cards can be used on the channelized OC-12/STM-4 MDA.
Each channelized OC-12/STM-4 supports 512 channels with DS-0 timeslots that are used in the
DS-1/E-1 channel-group. DS-3 TDM channels can be further channelized to DS-1/E-1 channel
groups. An E3 TDM channel cannot be channelized and can only be configured in clear channel
operation.
