The UDS1 Interface circuit pack provides an interface to the DS1 facility.
The maintenance strategy for the TN464 UDS1 Interface circuit pack (UDS1-BD) is very similar
to the maintenance strategy for the TN767 DS1 Interface circuit pack (DS1-BD). The same
commands are used for administering and testing the boards. The differences in maintenance
strategy between the boards are due to the UDS1 circuit pack’s direct interface to the Packet
bus which is used for ISDN-PRI signaling (ISDN-PLK). While both the TN464 and TN767 can
support ISDN-PRI B-Chels, ISDN-PRI D-chel signaling applications require a TN464 UDS1
circuit pack. See the following table for a list of USD1 Interface circuit packs:

Pack).
The UDS1 maintenance strategy includes logging inline errors reported by the UDS1 Interface
circuit pack, running tests for error diagnosis and recovery, and raising or clearing maintenance
alarms.
The TN464F or later circuit pack combined with an 120A1 CSU module forms an Enhanced
Integrated CSU. The 120A1 CSU module, when combined with the functionality provided by the
TN464F hardware and firmware, and switch software, provides functionality equivalent to an
external stand-alone ESF T1 CSU. The 120A1 CSU module connects to the TN464F circuit
pack on the I/O connector panel on the back of the port carrier. The CSU module thus becomes
an integrated part of the system. Throughout the document, the term 120A1 will mean a 120A1
or higher suffix CSU module.
