DS1 CONV-BD

DS1 Converter (Also called DS1 CONV)

MO's Name (in

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 CONV complex is part of the port-network connectivity (PNC) consisting

of two TN574 DS1 Converter or two TN1654 DS1 Converter circuit packs

connected by one to four DS1 facilities. It is used to extend the range of the

32-Mbps fiber links that connect PNs to the Center Stage Switch, allowing PNs to

be located at remote sites.

The TN1654 DS1 Converter Circuit pack is a redesign of the TN574 DS1

Converter board. The TN1654 provides functionality equivalent to the TN574 but

also adds a 32-Channel E1 interface for international support as well as

circuit-switched wideband connections (NxDS0). The TN1654 is supported

beginning with DEFINITY Release 5r.

Every error condition reported by the firmware is associated with background

tests that the firmware runs autonomously. Demand tests that are executed by

the maintenance software do not cause any new error generation by the firmware.

However, Failure Audit test (#949) affects auditing of the software error log by

forcing the firmware to report the pending errors again.

Maintenance of the DS1 facilities themselves is covered under the "DS1-FAC"

The DS1 CONV complex can extend a fiber link between two EIs or between a

PN EI and an SNI. Fiber links between two SNIs or between a port network and

the Center Stage Switch (CSS) cannot be extended.
