Chapter 6 Card and Service Configuration

Eight-Port Circuit Emulation Service Modules

E1-signalling specifies the E1 signalling. The possible entries are

CAS, which specifies CAS and no CRC

CAS_CRC, which specifies CAS with CRC

CCS, which specifies CCS and no CRC

CCS_CRC, which specifies CCS with CRC

CLEAR: CLEAR channel

Step 3 Create a logical port with addport if the application requires N x 64Kbps channels:

addport <port_num> <line_num> <begin_slot> <num_slot> <port_type>

port_num is the logical port number in the range 1–192 for T1 or 1–248 for E1

line_num is the number of the physical line in the range 1–8

begin_slot is the beginning timeslot number in the frame: for T1, 1–24; For E1 2–32 with CCS signalling or 2–16 and 17–32 with CAS signalling

num_slot is the number of timeslots in the frame for the current port (port_num)

port_type is: 1=structured 2=unstructured; 3=framing on VC disconnect

Step 4 Configure resources at the port level as needed by executing cnfportrscprtn:

cnfportrscprtn <port_num> <controller_name>

port_num is the logical port number in the range 1–192 for T1 or 1–248 for E1.

controller_name is the name of the network control application. Enter one of the following strings: PAR, PNNI, or MPLS.

Configuring Bulk Distribution and Redundancy

You can configure either bulk distribution alone, redundancy alone, or both of these features according to the restrictions in “Redundancy Support for the Eight-Port CESM.” On the CLI of the PXM1, execute addlink for bulk distribution (T1 only) before you execute addred for redundancy. To configure bulk distribution:

Execute addlink to create the links:

addlink <T3 line number> <T1 line number> <Target Slot number> <Slot line number>

T3 line number is the MGX-SRM-3T3/C line number in the format slot.line. The slot can be 15 or 31. The range for port is 1–3

T1 line number is the starting T1 line number within the T3 line. The range for the T1 line number is 1–28.

Target Slot number is slot number for the T1 service module.

Slot line number is T1 line number in the range 1–8.
