Bri (Switched) Configuration Model - Enterasys Security Router X-PeditionTM User Manual

ISDN Configuration

The above commands are mutually exclusive: you can enter one or the other per PRI interface, not
both. On the E1 NIM, 30 channels are controlled by ISDN, and 23 channels on the T1 NIM. Other
PRI commands include:
• bchan-number-order
calling-number
•
switch-type
•
BRI interfaces utilize a BRI-S/T or UNIM card. From a software perspective, S/T and U cards are
equivalent and all features supported on both cards are equivalent. The card type is significant
during installation only. In North America, the U card is connected directly to the ISDN service
jack, the S/T card requires an external NT1 device to be connected between the S/T card and the
service jack. Outside North America, only the S/T card is used with very few exceptions.
The two basic modes of operation of the BRI card are: CMD switched mode and leased line
(permanent) mode. Leased line mode is configured similar to T1/E1 channelized operation mode
- commands are entered at Controller configuration mode. BRI ISDN commands include:
answer1/2
•
• calling-number
• spid1/2
• switch-type
leased-line
