Channelized MDA/CMA Support
Channelized DS1/E1
Each 8-port channelized DS1/E1 CMA supports channelization down to DS0. Each 8-port
channelized DS1/E1 CMA supports 64 channel groups.
Channelized OC-3/STM-1 Circuit Emulation Services (CES)CMA and MDA
The channelized OC-3/STM-1/OC-12/STM-4 CES CMA/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 CMA is supported on the 7710 SR and 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 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 Signaling (CAS) options. CAS configuration must be identical for all channel groups
on a given DS-1 or E-1.
Circuits encapsulated in MPLS will use circuit pipes (Cpipes) to connect to the far end circuit.
Cpipes support either SAP-spoke SDP or SAP-SAP connections.
Circuits encapsulated in Ethernet can be selected as a SAP in Epipes. Circuits encapsulated in
Ethernet can be either SAP-spoke SDP or SAP-SAP connections for all valid Epipe SAPs. An EC-
ID and far-end destination MAC address must be configured for each circuit.
