ONFIGURATION
As you can see, the state of interface Bri 2/0:1 is up, its speed is 128 kbps, and
channels (timeslots used) B1 and B2 are in use; the state of Bri 2/0:2 is down, and
the field of timeslots used is NULL.
Network requirements
Router D is connected to a DMS100 switch of the carrier, using the access number
of 8810148. The ISDN lines on interface BRI 2/0 are allocated two SPIDs and LDNs;
they are:
spid1 = 31427583620101, LDN1 = 1234567
spid2 = 31427583870101, LDN2 = 7654321
In addition, the username and password for dialing are user and hello respectively.
Router D needs to place an MP call on interface Bri 2/0 to obtain an address from
the carrier for accessing the Internet.
