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 MO name
for the DS1 CONV circuit pack is DS1C-BD, and the MO 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 higher-suffixed) SNI board must also be used when connecting to the
TN1654 DS1 CONV board. See section DS1C-BD for information about 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 PNs to the Center Stage Switch, allowing PNs 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 either
background or on-demand tests from maintenance software. The overall
maintenance software strategy includes demand tests, recovery strategies, error
and alarm logging, and periodic audits.

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).
f is the DS1 facility (a, b, c, or d). See Chapter 7, or the DS1C-BD section, for identification of DS1
facility LEDs.
