DS1-FAC (DS1 Facility)
The DS1-FAC is a part of the DS1 Converter (DS1 CONV) Complex. The DS1
CONV Complex consists of two TN574 DS1 CONV circuit packs or two TN1654
DS1 CONV circuit packs connected by one to four DS1 facilities. The
maintenance object name for the DS1 CONV circuit pack is DS1C-BD, and the
maintenance object name for the connected DS1 facilities is DS1-FAC.

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 DS1 CONV circuit pack is not compatible with the TN574 DS1
CONV board or the Y-cable used to interface to the TN574 DS1 CONV. A
TN573B or later suffix SNI board must also be used when connecting to the
TN1654 DS1 CONV board. See section DS1C-BD for information on both DS1
CONV circuit packs.

The DS1 CONV Complex is a part of the Port Network Connectivity (PNC). The
DS1 CONV Complex 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 DS1 CONV circuit pack contains on-board firmware that detects DS1 facility
alarms and errors, communicates status to maintenance software, and runs tests
in the background or on demand from maintenance software. The overall
maintenance software strategy includes demand tests, recovery strategies, error
logging and alarm logging, and periodic audits.

in the background or on demand from maintenance software. The overall
maintenance software strategy includes demand tests, recovery strategies, error
logging and alarm logging, and periodic audits.
Every error condition reported by the firmware is associated with the background
tests that the firmware runs autonomously. Demand tests that are executed by
the maintenance software do not have any functionality that would effect any
additional error manipulation by the firmware. However, the Failure Audit test
tests that the firmware runs autonomously. Demand tests that are executed by
