DS1-BD
1 UU is the universal cabinet number (1 for PPN, 2 - 3 for EPNs). C is the carrier
designation (A, B, C, D, or E). SS is the number of the slot in which the circuit pack
resides (01 to 21).
The DS1 Interface circuit pack provides an interface to an external DS1 facility
and supports 24 DS0 channels carried on a 1.544 Mbps DS1 link. These DS0
channels can be administered as either trunks to other switches or lines to
off-premises stations. The TN464C and later suffix Universal DS1 Interface also
supports a 32-channel interface on a 2.048Mbps link. The functions and
maintenance strategy for the TN464 circuit packs are covered under a separate
maintenance object, UDS1-BD.
DS1-BD maintenance logs in-line errors reported by the DS1 Interface circuit
pack, runs tests for error diagnosis and recovery, and raises and clears alarms.
The following table shows the capabilities of each DS1 circuit pack. The TN722
and TN722B are not supported on G3r V1 or later systems.

ISDN-PRI Trunk signaling (for example, Q.921, Q.931) requires a TN464D and is
handled by system software. The TN464 is covered in the "UDS1-BD (UDS1
Interface Circuit Pack)" section of Chapter 9.
Each trunk and line have their own maintenance strategies. However, they all
depend on the health of the DS1 Interface circuit pack. Refer to the following
sections for details: TIE-DS1, CO-DS1, DID-DS1, OPS-LINE, ISDN-TRK, and
ISDN-PLK. Signaling over the DS1 link must be synchronized between the
transmitting and receiving ends to ensure error-free communication. Refer to
"SYNC (Synchronization)" for details.
