Intraplex® DS-967 Data Module

Simulcast-Ready Synchronous Data Transport Module

The Intraplex® DS-967 synchronous data transport module provides full-duplex transmission of five 9.6 kb/s synchronous data channels using only one time slot (DS0) in T1 (1.5 Mb/s) or E1 (2 Mb/s) circuits. The DS-967 also transports 10 contact closure signals in each direction within the same time slot.

The module plugs into Intraplex access products, allowing low-speed data channels to be combined with other types of payload channels for transport over T1, E1, or IP networks.

In conjunction with the Intraplex SynchroCast3™ simulcasting system, the DS-967 module enables alignment of 9.6 kb/s synchronous data channels for implementation of conventional digital simulcast systems. The same precision GPS-based phase alignment currently deployed in analog conventional simulcast systems across the country is now available for digital system implementations.

Features

  • One-way or full-duplex operation
  • Loopback of all channels at the receive side
  • Optional timing inversion
  • Module occupies one user-selectable time slot
  • Simulcast compatibility with SynchroCast3™ simulcasting system
  • Communications interface with Windows®-based IntraGuide® Configuration and Management Software
  • Compatible with Intraplex NetXpress™, NetXpress LX™, and Access Server multiplexers for use in T1, E1, and IP networks

Data
Data PortFull-duplex, 5 independent data channels
Clock Data RatesA common rate of 9.6 kb/s

Signaling
E&M Signaling (10 contact closures in each direction)
M-Lead InputSwitching threshold +2.5 V
Input impedance 10 K ohms pull-up to +5 V
Vin H = 3.0 V minimum
Vin L = 2.0 V maximum
E-Lead OutputIdle = Open
Busy = Less than 30 ohms to ground
On loss of power or frame synchronization, the E-lead will go to the idle (open) state

Delay9.6 kb/s synchronous data end-to-end processing delay is 4.2 mS

Status MonitoringRemote status monitoring of E-lead and M-lead state
Remote status monitoring of both local and far-end receive synchronization and mode
