The DS1-FAC is a part of the DS1 Converter (DS1C-BD) complex. The DS1C-BD complex<br />

consists of two TN574 DS1C-BD circuit packs or two TN1654 DS1C-BD circuit packs<br />

connected by one to four DS1 facilities. The MO name for the DS1 converter circuit pack is<br />

DS1C-BD, and the MO name for the connected DS1 facilities is DS1-FAC.<br />

The TN1654 DS1 Converter circuit pack is a redesign of the TN574 DS1 Converter board. The<br />

TN1654 provides functionality equivalent to the TN574, and adds a 32-channel E1 interface for<br />

international support as well as circuit-switched wideband connections (NxDS0).<br />

The TN1654 DS1 converter circuit pack is not compatible with the TN574 DS1 converter board<br />

or the Y-cable used to interface to the TN574 DS1 converter. A TN573B (or higher-suffixed) SNI<br />

board must be used when connecting to the TN1654 DS1 converter board. See DS1C-BD for<br />

information about both DS1 converter circuit packs.<br />

The DS1 converter complex is a part of the port-network connectivity (PNC). The DS1 converter<br />

complex is used to extend the range of the 32-Mbps fiber links that connect PNs to the Center<br />

Stage Switch, allowing PNs to be located at remote sites.<br />

The DS1 converter circuit pack contains on-board firmware that detects DS1 facility alarms and<br />

errors, provides status for maintenance software, and runs either background or on-demand<br />

tests.<br />

DS1 converter circuit packs are connected to the Expansion Interface (EI) circuit packs (TN570)<br />

and the Switch Node Interface (SNI) circuit packs (TN573) as shown in Figure 53: DS1<br />

Converter Complex and the DS1 Facilities.<br />
