16xE1Trib Module
The Wayside Traffic Module supports 16xE1 tributary circuits. Each is accessed on an
RJ-45 connector.
• Options are provided for 75 ohms unbalanced or 120 ohms balanced.
• The module supports trib and radio facing loopbacks, AIS insertion, and a PRBS
generator and receiver for trib BER measurement.
• Line isolation and surge protection are included.
Trib cable options include:
• An RJ-45 to 2xBNC cable assembly.
• An RJ-45 to RJ-45 straight cable assembly for extension to an RJ-45 patch panel.
• An RJ-45 to RJ-45 cross-over cable assembly for use between IDUs at repeater or
branch sites.
• An RJ-45 to wire-wrap cable assembly.
For more information on cable assemblies and connector pin-outs refer to
Appendix A.
Auto Insertion of AIS or PRBS on Tribs
When a link demodulator-unlock occurs, it inserts an alarm signal AIS on all trib
circuits
towards the customer. (Demodulator unlock may occur under severe fading
or an equipment fault).
An on-board master clock maintains customer-facing clocking references when the
expected signal input and associated clocking reference from its link is missing, or
below the minimum level required.
NOTE:
AIS may also be forced onto a tributary using the Systems Control
screen.
