Channelized MDA/CMA Support

Channelized DS-3/E-3 ASAP MDA (4-Port)

The 4-port MDA provides 4 ports configurable as DS-3 or E-3. The MDA has eight (8) 1.0/2.3
connectors and accepts up to eight (8) DS-3/E-3 coax patch cables.
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 DS-1/E-1 channel can then be further channelized
down to DS-0s. E-3 ports do not support channelization, only clear channel operation.

Channelized DS-3/E-3 ASAP MDA (12-Port)

The 12-port MDA provides 12 ports configurable as DS-3 or E-3. The MDA has twenty-four (24)
1.0/2.3 connectors and accepts up to twenty-four (24) DS-3/E-3 coax patch cables.
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 DS-1/E-1 channel can then be further channelized
down to DS-0s. E-3 ports do not support channelization, only clear channel operation.

Channelized OC-3/STM-1 Circuit Emulation Services (CES) CMA and MDA

The channelized OC-3/STM-1/OC-12/STM-4 CES MDAs (c1-choc3-ces-sfp / m1-choc3-ces-sfp,
m4-choc3-ces-sfp, m1-choc12-ces-sfp) provide an industry leading consolidation for DS-1, E-1
and n*64kbps for CES. The CES MDAs are supported on IOM-2 and IOM-3XP in the 7750 SR.
The channelized OC-3/STM-1/OC-12/STM-4 CES CMA/MDAs support CES. Circuit emulation
services are interoperable with the existing 7705 SAR and 7250 SAS circuit emulation services.
They are also interoperable with the 1850 TSS-5 circuit emulation services.
Two modes of circuit emulation are supported, unstructured and structured. Unstructured mode is
supported for DS-1 and E-1 channels as per RFC4553 (SAToP). Structured mode is supported for
n*64 kbps circuits as per RFC 5086, Structure-Aware Time Division Multiplexed (TDM) Circuit
Emulation Service over Packet Switched Network (CESoPSN). In addition, DS-1, E-1 and n*64
kbps circuits are also supported as per MEF8, Circuit Emulation Services over Ethernet
(CESoETH) (Oct 2004). TDM circuits are optionally encapsulated in MPLS or Ethernet as per the
applicable standards.
All channels on the CES CMA/MDA are supported as circuits to be emulated across the packet
network. This includes DS-1, E-1 and n*64 kbps channels. Structure agnostic mode is supported
for DS-1 and E-1 channels. Structure aware mode is supported for n*64 kbps channel groups in
DS-1 and E-1 carriers. N*64 kbps circuit emulation supports basic and Channel Associated
