Task 4. Configuring the Serial Interfaces

Step 2 Verify that ISDN is functioning properly, and the serial channels are up:

• Check the ISDN status. Confirm that Layer 1 reports ACTIVE, and the display field

MULTIPLE_FRAME_ESTABLISHED appears at Layer 2. For PRI lines, the terminal endpoint

identifier (TEI) is always 0. The Layer 3 status reports no active calls.

Global ISDN Switchtype = primary-ni

ISDN Serial1/0/0:4:23 interface

dsl 0, interface ISDN Switchtype = primary-ni

Layer 1 Status:

ACTIVE

Layer 2 Status:

TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED

Layer 3 Status:

0 Active Layer 3 Call(s)

Activated dsl 0 CCBs = 0

The Free Channel Mask: 0x807FFFFF

Total Allocated ISDN CCBs = 0

• Look at the status of the DS0 channels. In this example, 23 DS0s are idle. The 24th channel is

reserved for PRI D-channel signaling.

Step 3 Test the configuration by sending a POTS call into the Cisco AS5800 network access server (NAS). If

the modem answers (you hear modem squelch), the configuration works. In Figure 2-5, a different

telephone number is associated with each end of the connection.
