The DS1-FAC is a part of the DS1 Converter (DS1C-BD) complex. The DS1C-BD complex
consists of two TN574 DS1C-BD circuit packs or two TN1654 DS1C-BD circuit packs
connected by one to four DS1 facilities. The MO name for the DS1 converter 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, and adds a 32-chel E1 interface for
international support as well as circuit-switched wideband connections (NxDS0).
The TN1654 DS1 converter circuit pack is not compatible with the TN574 DS1 converter board
or the Y-cable used to interface to the TN574 DS1 converter. A TN573B (or higher-suffixed) SNI
board must be used when connecting to the TN1654 DS1 converter board. See DS1C-BD for
information about both DS1 converter circuit packs.
The DS1 converter complex is a part of the port-network connectivity (PNC). The DS1 converter
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 converter circuit pack contains on-board firmware that detects DS1 facility alarms and
errors, provides status for maintenance software, and runs either background or on-demand
tests.
DS1 converter circuit packs are connected to the Expansion Interface (EI) circuit packs (TN570)
and the Switch Node Interface (SNI) circuit packs (TN573) as shown in Figure 18: DS1
Converter Complex and the DS1 Facilities.
