四、direction for use

4.1 Description of equipment composition

As shown in the figure below, the equipment is composed of power supply, motherboard, etc. There are 30 slots on the motherboard, which can be inserted into FXO / FXS / magnet, RS232, hotline and other business cards.

4.2 The front panel instructions

• switch declaration

ON: Power is on.

OFF: Power-off.

2, the alarm indicator light instructions

AIS: Frame lost step alarm, when the local device frame lost step, the red light is on.

LOS: Red light is on when the E1 signal is lost.

RA: Bureau alarm. The red light is on when the opposite-end device frame loses out.

2M: E1 input indication. Corresponding green indication when the E1 input signal is normal

The light is on; the corresponding green indicator is off.

O / S: O local terminal work indicator, S remote terminal work indicator.

1~30: Road pickup / data receiving indication. For FXS / FXO, the corresponding path

The indicator light, hang up out. For RS232 data, when the data is receiving or sending data, the indicator light of the corresponding road is always on, and when there is neither receiving or sending data, the indicator light of the corresponding road is extinguished.

RUN: blinking during normal operation.

PW: Power supply indicator light, light on when normal (green).

4.3 Description of the rear panel

P1~30: The RJ 45 interface. See Table 3 for the pin arrangement of 30-channel voice / data access port and RJ 45 interface

E 1 IN / OUT: The BNC interface. OUT is the output and INis the input.

120 Ω: RJ 45 interface. The 120 Ω (Balanced) E1 access port.

A C220V: 220V power supply access port

-48V DC: -48V DC power access port, GND is the power source.

44 Equipment opening instructions

No setup is required when the device is enabled. It should be noted that the equipment is divided into bureau and household end. When the equipment is installed, pay attention to check the identification on the equipment. The voice interface of the terminal device connects to the user line of the switch, and the voice interface of the terminal device connects to the telephone.
