19.2.1 Appearance and functions
Appearance
Function
The OPCOM3500E-MULTI is a multi-service access card used for accessing voice and
data services.

Provide 8 FXS/FXO voice interfaces, four 2/4W interfaces, and 4 data interfaces. The
interface name printed on the panel are VOICE, 2/4W, and DATA respectively.

FXS/FXO interfaces occupy 1–8 E1 timeslots. 2/4W interfaces occupies 9–12 E1
timeslots. Each channel of the data interfaces occupies 2 timeslots and 4 data channels
occupy 13–15 and 17–21 E1 timeslots. In addition, the E1 is in PCM30 mode.

FXS/FXO interfaces support FXS and FXO modules, which is decided by the internally-
inserted module. Up to 4 modules are available. You can insert fewer modules or insert
hybrid modules. When inserting hybrid modules, you must insert the FXS module first
and then insert the FXO module.

The voice gain of FXS/FXO interfaces is adjustable.

RX A/D ranges from -3 dB to 13 dB. By default, it is set to 0 dB.

TX D/A ranges from -13 dB to 3 dB. By default, it is set to -3.5 dB.

FXS/FXO interfaces support configuring signaling modes (original signaling and
reversed signaling) and signaling types (a-bit/b-bit signaling).

FXS/FXO interfaces support the hotline mode but do not support ringback tone.

2/4W interfaces support configuring 2/4W mode but do not support signaling.

The voice gain of the 2/4W interfaces is adjustable. The RX A/D ranges from -11 dB to
+19 dB. The default value is set by the DIP switch. The TX D/A ranges from -24 dB to
+7dB. The default value is set by the DIP switch.

2/4W interfaces support internal loopback and external loopback.

Data interfaces supports V.24 and RS485 modules, which is decided by the internally-
inserted module. Each module outputs 2-way data.

V.24 interfaces can work in synchronous mode (V.24) or asynchronous mode (RS232).
RS485 interfaces can work in full duplex mode (RS422) or half duplex mode (RS485).

Four-way RS232 interfaces occupy 1-way transparent transmission E1 respectively. The
E1 TX (in aggregation card direction) clock can be a local crystal oscillator or a SDH
system clock.

Clock phased of both directions of V.24 interfaces are adjustable.

Except for the RS485 mode, data interfaces support local internal loopback and external
loopback.

In RS232 mode, sampling frequency of interfaces can be set to 64 KHz, 128 KHz, or
2048 KHz and the related speeds are set to 9.6 Kbit/s, 19.2 Kbit/s, and 460.8 Kbit/s.

In V.24 mode, sampling frequency of interfaces can be set to 64 KHz or 128 KHz and
the related speeds are set to 9.6 Kbit/s and 19.2 Kbit/s.

In RS485/RS422 mode, sampling frequency of interfaces can be set to 64 KHz or 128
KHz and the related speeds are set to 9.6 Kbit/s and 19.2 Kbit/s.

Support upgrading the card online.
19.2.2 Slots
The OPCOM3500E-MULTI can be plugged into slots 1–5 and 8–12 on the iTN2100.
