Model 2130 Characteristics

Telemetry Channel Interface

Five Communication Ports All ports RS-422
(RS-530/RS-449/V.35 compatible)
15-pin female D-Sub (DB15F) shielded Asynchronous (async) or Synchronous (sync)
Async Mode (bridge to radio):
19.2 kb/s, 8/N/1, all ports
Sync Mode (bridge to bridge):
19.2 to 75 kb/s, DTE, all ports
Port 5, switch selectable DTE or
64 kb/s DCE
Mode automatically sensed at startup
Bad packet suppression optional
DTE accepts clock, DCE supplies clock
Ports 1 & 2 Ring or local drop
Ports 3 & 4 Local drop
Port 5 Local drop or connection to another bridge
Bridging Modes, Ring Hub plus Selective
Bridging Modes, Linear Hub, Switch Polls and Switch All
