Setting up a Frame Relay Connection
Step3 If not configured, configure the T1 line to the frame relay equipment using the cnfln
command. Specify parameters as appropriate.
If not enabled, enable the port to the frame relay equipment by performing an addport
command using the parameters as follows:
For port number, specify an unused port number (1 to 96).
For line number, specify the FRSM line used to connect to the frame relay equipment
(1 to 4, with 1 being the top line).
For DS0 speed, specify either “1” for 56K or “2” for 64K bits per second.
For beginning timeslot, specify the beginning timeslot in the T1 or E1 line.
For number of timeslot, specify the number of consecutive T1 or E1 timeslots to be used
for the connection.
Step4 Enable the frame relay channel by performing an addchan command.
Select network interworking or service interworking in the chan_type parameter. 1 is for
network interworking.
For channel number, enter a value between 16 and 271. THIS WILL BE THE SAME
NUMBER SPECIFIED IN THE VCI FIELD TO/FROM THE BPX SWITCH.
For port number, enter the port number previously enabled.
For DLCI, enter a DLCI number to be used in communicating with the frame relay
equipment.
NoteOnce a service module channel is started in the MGX 8220 shelf, the T3 line to the
BPX switch is automatically up, configured and started by the MGX 8220 shelf and no action is
required by the operator.
NoteRemember that this process must be repeated at the remote end to establish the segment at
that end.
At this point the MGX 8220 shelf segment is up with default parameters.
