Cisco MGX 8220 Installation and Configuration

Release 5.0, Part Number 78-6430-03 Rev. D0, November 2003

Chapter   

Circuit Emulation Service Modules

Circuit Emulation Service Module (8-port)

The 8-port Circuit Emulation Service Module (CESM) is a two-card set consisting of an CESM function 
module front card and either a 8-T1 or a 8-E1 line module back card. T1 lines use RJ48 connectors, E1 
line module cards use either RJ48 or SMB connector types. The possible line modules are

•

AX-RJ48-8T1-LM

•

AX-R-RJ48-8T1-LM

•

AX-RJ48-8E1-LM

•

AX-R-RJ48-8E1-LM

•

AX-SMB-8E1-LM

•

AX-R-SMB-8E1-LM

Up to 10 CESMs may be installed in a shelf in slots 5 through 14. For T1 line versions, 1:N redundancy 
is supported either through redundant line modules or through the SRM-T1E1 board. Likewise, for 
T1/E1 versions, BERT and loopbacks are supported using the SRM.

A 1:N redundancy for E1 version is provided through redundant line modules only.

The main function of the CESM cards is to provide a constant bit rate (CBR) service for T1/E1 ports 
over ATM network. 

The CESM converts DS1/E1 or data streams into CBR AAL1 cells for transport across the ATM 
network. The T1/E1 versions support a choice of structured or unstructured data transfer on a 
per-physical-interface basis.

The CESM card supports loopback diagnostics features through the addlnloop command.

Note

The addchanloop command is not supported in the 8-port CESM. 

Refer to the Cisco MGX 8220 Command Reference for details of these commands.

T1/E1 Structured Data Transfer

The T1/E1 structured data transfer mode supports

•

Synchronous timing only.

•

A nx64 Kbps Fractional DS1/E1 service with contiguous time slots. Any nx64 kbps channel can be 
mapped to any VC. Both SF and ESF framing modes are supported.

•

For AAL1 interworking conversion only, CAS robbed bit for T1 (ABCD for ESF and SF frames) 
and CAS for E1 (Channel 16). 

•

CCS channel transparently as data.

•

Choice of partially filled cells.

•

Idle Suppression/Detection for 1x64 CAS connections only.

T1/E1 Unstructured Data Transfer

The T1/E1 unstructured data transfer mode supports:

•

Both synchronous and asynchronous clocking.
