DS1 CONV-BD
DS1 Converter (Also called DS1 CONV)
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 EPNs to either the PPN or the Center Stage
Switch, allowing EPNs 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, the Failure Audit test #949 effects 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 an
EPN EI and an SNI. Fiber links between two SNIs or between the Processor Port
Network (PPN) and the Center Stage Switch (CSS) cannot be extended.

The TN1654 board is not compatible with the TN574 board. A DS1 CONV
Complex may consist of two TN574 boards or two TN1654 boards but a TN574
cannot be combined with a TN1654 in the same complex. A system with multiple
DS1 CONV-remoted EPNs may contain DS1 CONV Complexes of both types,
