Enterasys Networks X-PeditionTM manual BRI Switched Configuration Model

ISDN Configuration

•The channel-groupcommand for point-to-point connections.

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-orderselects a channel from B1 (ascending) or B23/B32 (descending).

•calling-numberconfigures an outgoing ISDN calling number.

•switch-typespecifies the Central Office ISDN 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 adds a called number:subaddress to be screened.

• calling-numberadds a calling number included in outgoing calls.

• spid1/2 sets a Service Profile ID string calling-number: subaddress.

•switch-typeselects the interface ISDN switch type.

•leased-linesets a BRI interface to support leased lines.

BRI (Switched) Configuration Model

Figure 11-1, shown below, illustrates how Dialer and BRI interfaces are configured on the XSR’s BRI NIM card (XSR 1800/3000 Series) as well as how those interfaces correlate to dialer and access lists, map classes, and dialer pools
