BRI-U4.
6. Under Hardware, select the type for each loop:
• for a BRI card, select T or S if the card type is BRI-ST
• for a BRI-U2 or BRI-U4 card, select LT or NT
7. If the card uses a T or NT loop, enter the following
information, as supplied by your service provider:
• the SPID assigned to the loop
• the number of B-channels associated with each SPID
• the Network DNs used with the network SPID
• the call type of the Network DN
Repeat the programming for the second network SPID, if
any.
If the T or NT loop is used for D-packet service:
• turn on the service
• assign the appropriate S-loop mapping for BRI-ST
cards or LT-loop mapping for BRI-U2 or U4 cards
• assign the TEIs to the loop. These are provided by the
telco to support a point-of-sale terminal adapter or
other D-packet service device.
If the loop type is S, select the sampling used on the loop.
If the loop type is S or LT:
• assign ISDN DNs to the loop
• designate one of the assigned ISDN DNs to be the DN
for the loop (Loop DN).
Note: You can have a maximum of 30 ISDN DNs on your
system. The default ISDN DN range is 667-696 on
