NTRB21 DTI/PRI/DCH TMDI card
553-3011-100
Standard 14.00
January 2002
Overview
The NTRB21 TMDI (DTI/PRI/DCH) card is required to implement PRI on
the Meridian 1 Option 11C system. It is supported in the Main and IP
expansion cabinets.
The TMDI feature introduces the software changes required for an
Option 11C system to support the new TDMI pack. These changes include
the introduction of a new prompt to replace a function that was handled by a
dip switch on the NTAK09, as well as an extra loadware application to handle
Layer 1, and changes to make the existing loadware files into 32 bit format
instead of the original 16 bit format. To provide CEMUX communication
with the card, changes are also required to create an I/O entry for the card. In
addition the NTRB21 has a built-in downloadable D-channel.
This card requires that the Option 11C be equipped with at least Release 24
software.
This card replaces the NTAK09 described in “NTAK09 1.5 Mb DTI/PRI
card” on page 447. This feature does not affect the NTAK09 functionality,
configuration, or maintenance in any way. Aside from changes to the
configuration and maintenance of the pack, there are no other changes seen
by the users, and call processing is not affected.
