ELMC Five Port Bridge
Model 2130

2130 ELMC Five Port Data Bridge

• Up to five way bi-directional bridging
of Extended Link Monitor Channel
(ELMC) protocol
• Two ports can create ELMC ring
protection
• Multiple bridge concatenation
for bridging beyond five ports
• Format conversion between async
19,200 baud and synchronous
(e.g. channel bank) connections
• 1 RU high
• Multiple rack mounting positions
• 18 to 56 VDC floating power supply

Key Features:
• Ring and Linear Operation
• Bridging and Filtering
• Embedded Craft Interface
• Remote Access
• Telemetry Performance Data
• Wide Range DC Power Input
• Proven ELMC Compatibility
• Synchronous and Asynchronous Operation

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
plus Selective
Performance Data Packets, buffers, comm errors and
ring faults

Craft Configuration Port
