1. UU is the universal cabinet number (1–64 for ATM PNC, 1–44 for CSS PNC). C is the carrier designation (A,
B, C, D, or E). SS is the number of the slot where the circuit pack resides (01–21).
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 (or higher-suffixed) Universal DS1 Interface
also supports a 32-channel interface on a 2.048-Mbps link. The functions and
maintenance strategy for the TN464 circuit packs are covered under a separate
MO,

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
