17.1.1 Appearance and functions
Appearance Function
The OPCOM3500E-8V35 is an 8-way V.35 data service card on the iTN2100.
 Map V.35 data within itself to the VC12 of SDH directly or indirectly (V.24 data is
aggregated by the OPCOM3500E-DXC-DS0 first and then mapped to the VC12 of the
SDH), and each way of V.35 data occupy a way of E1 signals.
 Provide four HDB26 interfaces. Each interface transmits two ways of V.35 data.
 Support application in DCE mode.

Support independent configuration of bandwidth for each V.35 channel. You can set the
E1 channel to framed or unframed:
 In framed E1, set V.35 bandwidth to N×64 Kbit/s (N: 1–31).
 In unframed E1, set V.35 bandwidth to 2 Mbit/s.
 Support timeslot automatical track in TS0 transparent transmission.
 Support local crystal oscillator, E1-1 recovery clock, or E1-2 recovery clock as clock
source.
 Support TX and RX phase adjustment on each V.35 interface independently.

The V.35 data channel supports independent configurations of each interfaces and two
loopback modes:

Outer loopback on the V.24 interface side

Inner loopback on the V.24 interface side
 Support E1 BERT. When you send test codes to the backplane, you can test only one E1
once.
 Support hot swapping.
17.1.2 Slots
The OPCOM3500E-8V35 can be plugged into slots 1–5 and 8–12 on the iTN2100.
