1. UU is the universal cabinet number (1–64). C is the carrier designation (A, B, C, or D). SS is the number of the
slot where the circuit pack resides (01–10).
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-LNK). While both the TN464 and TN767 can support
ISDN-PRI B channels, ISDN-PRI D-channel signaling applications require a
TN464 UDS1 circuit pack. See the following table for a list of USD1 Interface
circuit packs:

UDS1 Interface circuit pack Maintenance documentation provides a strategy for
maintaining the UDS1 Interface circuit pack. The maintenance strategy deals with
logging the in-line 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 behind the port carrier. The CSU module, thus becomes an
integrated part of the S8700 IP Connect system. Throughout the document, the
term 120A1 will mean a 120A1 or later suffix CSU module.
