DS1-BD (DS1 Interface Circuit Pack)
MO Name in Log Alarm
Level
DS1-BD MAJ
MIN
The DS1 Interface circuit pack provides an interface to an external DS1 facility and supports 24
DS0 chels carried on a 1.544-Mbps DS1 link. These DS0 chels can be administered as either
trunks to other switches or lines to off-premises stations. The TN464C (or later-suffixed)
Universal DS1 Interface also supports a 32-chel interface on a 2.048-Mbps link.
The functions and maintenance strategy for the TN464 circuit packs are covered under a
separate MO, UDS1-BD (UDS1 Interface Circuit Pack).
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 or higher suffix,
TN2464, or TN2242 (tie trunk signaling only) and is handled by system software. The TN464,
TN2464, and TN2242 are covered in UDS1-BD (UDS1 Interface Circuit Pack).
Each trunk and line have their own maintenance strategies. However, they all depend on the
health of the DS1 Interface circuit pack. See the following sections for details:
● TIE-DS1 (DS1 Tie Trunk)
● CO-DS1 (DS1 CO Trunk)
● DID-DS1 (Direct Inward Dial Trunk)
● OPS-LINE (DS1 Off-Premises Station Line)
● ISDN-TRK (DS1 ISDN Trunk)
● ISDN-PLK (ISDN-PRI Signaling Link Port).
