[comp.dcom.telecom] Request for DS3 Tranmsit/Receive Equipment

ogmundso@eric.mpr.ca (Pat Ogmundson) (06/01/89)

I am interested in obtaining a piece of equipment
to tranmsit and receive DS3 (45.570 MBit/s +/- 20ppm)
signals. Schematically:

                           ________________________
        Binary (TTL?) ---->| Line Code Conversion |----> DS3 (B3ZS)
                           | and Pulse Shaping    |
                           |                      |
        Binary (TTL?) <----| Line Code Conversion |<---- DS3 (B3ZS)
                           | and Clock Recovery   |
                           ------------------------
                                        |
                                        |
        DS3 Clock <----------------------

I need this hardware to interface my binary data source/sink to
a DS3 fibre optic tranmsission system.
This is a prototype digital transmission system, and I am trying
to avoid DS3 equipment development.

Ideally I would like to obtain a PCB module, but if its a
stand-alone piece of hardware (or if a portion of a larger
piece of equipment could be made available) I  would be interested.
