2.2 DESCRIPTION
The Patton Model 2070 Miniature Interface Converters allow a
synchronous V.24, V.35, or X.21 device to communicate bi-directionally
over the G.703 co-directional PCM network. Supporting internal,
external DTE timing or G.703 network generated timing, the Model
2070 is perfect for networking applications that require a single 64
kbps data channel.
The Model 2070 connects directly to the synchronous DTE using
a DB-25 connector (Model 2070/Ax), an M/34 connector (Model
2070/Cx) or a DB-15 connector (2070/Dx). A 120 ohm twisted pair
telephone port provides the interface for the G.703 network.
Additionally, 75 ohm terminations can be made using the Patton Model
460 (G.703 balun).
Diagnostics include Local Loopback and G.703 Loopback testing.
Synchronous clock jitter is attenuated in accordance with the G.823
specification.
