NTRB21 TMDI card

The NTRB21 TMDI card provides 1.5 MBit/s Digital Trunk Interface or Primary Rate Interface functionality on the system. The NTRB21 has a built-in, downloadable D-channel.

The NTRB21can be equipped with the NTAK09 DTI/PRI card (with the NTBK51 downloadable D-channel daughterboard) and the NTAK93 DCHI daughterboard.

Note: A TMDI D-channel programmed as a backup D-channel against a non-TMDI primary D-channel is not supported. Backup D-channels are supported only when programmed against TMDI primary D-channels.

Figure 76 "NTRB21 TMDI card faceplate" (page 198) shows a faceplate of the NTRB21 TMDI card.

Shelf slot assignments

For Small Systems, the NTRB21 can be placed in main and expansion cabinets in any single card slot given in Table 74 "Shelf slot assignments for NTRB21, NTAK09, and NTAK20" (page 202).

The Media Gateway Expansion does not support digital trunks (DTI/PRI).
