Create a T1 to a Virtual Interface Cross-Connect
For this example we will configure a T1 WAN interface with DS0s 1 through 10 for data.
The following steps assume the Global Configuration mode is currently active. Verify that
the prompt of your unit displays (config)#.
1. Enter interface t1 1/1 to activate the interface configuration mode for the T1 WAN interface.
2. Enter tdm-group 1 timeslots 1-10 to create a TDM group for DS0s 1-10 on the T1 network
connection (t1 1/1).
3. Enter no shutdown to activate the interface to pass data.
4. Enter exit to return to the Global Configuration mode.
5. Enter cross-connect 1 t1 1/1 1 frame-relay 1 to connect DS0s 1-10 of the T1 network
connection (t1 1/1) to the virtual frame-relay interface fr 1.
Alternately,
6. Enter cross-connect 1 t1 1/1 1 ppp 1 to connect DS0s 1-10 of the T1 network connection
(t1 1/1) to the PPP interface labeled 1.
Configure the Multilink PPP interface
The following steps assume the Global Configuration mode is currently active. Verify the
prompt of the unit displays (config)#.
1. Enter interface ppp 2 to access the configuration parameters for the PPP interface.
2. Enter ip address 192.22.73.1 255.255.255.0 to assign an IP address to the PPP interface
using a 24-bit mask.
3. Enter ppp multilink to configure the PPP interface for multilink PPP.
4. Enter no shutdown to activate the interface to pass data.
5. Enter exit to return to the Global Configuration mode.
