Chapter
Setting up a Frame Relay Connection
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 56 kbps or 2 for 64 kbps.
For the 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.
Step 5 Enter the addchan command to enable the Frame Relay channel.
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.
Note Once 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.
Note Remember 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.
Establish the BPX-to-BPX Segment
The following steps should be performed to establish the required BPX-to-BPX segments.
1. Enter the addcon command at one of the BPX nodes (not both) as follows.
For slot number and port number, specify slot and port of the BNI port connected to MGX 8220.
For VPI, specify the slot number in the MGX 8220 shelf that contains the FRSM attached to the
BPX.
For VCI, specify the logical channel number (LCN) of the Frame Relay connection configured on
the local MGX 8220 shelf.
For Nodename, specify the nodename of the BPX at the other end of the connection.
For Remote Channel, specify the BNI slot and port number of the BNI port attached to MGX 8220
at the remote end. Specify the VPI as the slot number of the remote MGX 8220 FRSM connected
to the BPX and specify VCI as the LCN of the Frame Relay connection at the remote MGX 8220.
Specify the type of connection. ATFR when ForeSight is not being used and ATFST when
ForeSight is being used.
2. Enter the other addcon parameters of bandwidth, and so on.
