Configuring Packet Over SONET
14-5
n is the number of permitted negotiation attempts from 1 to 100.
3. To set the maximum PPP wait time for the network layer to negotiate before
disconnecting the PPP link on the POS interface when there is no activity on the
link, use the ppp timeout ncp command in Interface Configuration mode, as
shown in the following example.
MOT(config-if)#ppp timeout ncp <seconds>
where:
seconds is the number of seconds of inactivity before the PPP link is
disconnected; default is 10 seconds.
4. To set the maximum PPP wait time for a negotiation response before
disconnecting the PPP link on the POS interface when there is no activity on the
link, use the ppp timeout command in Interface Configuration mode, as shown
in the following example.
MOT(config-if)#ppp timeout retry <seconds>
where:
seconds is the number of seconds of inactivity before the PPP link is
disconnected; default is 10 seconds.
Configuring the Network Clock Source for SONET
The network clock source is set for the SONET link to avoid undesirable conditions
related to timing synchronization such as jitter and wander. Jitter refers to the
short-term instabilities in network signal timing. Wander refers to long-term random
variations of the significant instances of a digital signal from their ideal position in
time. The internal clock on the POS module is enabled by default so that it references
the network clock source for the BSR 64000.
