RFL DS-961DE Five-Port Multi-Rate
Synchronous Data Module
DESCRIPTION
The DS-961DE is a five-port multi-rate synchronous data channel module, designed for use in IMUX
2000 E1 Multiplexers. The module uses an RS-232C interface to enable transmission of up to five 9.6
kbps or two 19.2 kbps data signals over E1 and other digital communications facilities, using only one
64 kbps time slot.
The DS-961DE has three switch banks, one setup jumper, and four LEDs, one each for channels
transmitting, channels receiving data, no framing bit, and transmit fault.
The DS-961DE is remote-controllable when installed in an RFL remote controllable shelf. The
following module parameters can be configured remotely via SCB or locally via DIP switches.
User-adjustable switches and jumpers allow configuration of the following parameters:
o Data rate selection from 1200 bps to 19.2 kbps
o Optional three-channel operation (two at 19.2 kbps, one at 9.6 kbps)
o Selection of transmit timing or terminal timing
o Selectable transmit/receive direction for drop and insert operation
o Optional timing inversion
o Switchable loopback of all channels at the receive side
o Time slot selection
