Note:

1. At auto-negotiation mode, Ethernet electrical port supports HP auto-MDIX

function and it can check the transmission and receiving sequence and make

configuration. So both MDI and MDI-X interfaces are supported and both

cross line and direct line can be selected.

2. Network Management can be used for all the Ethernet ports except Data1

port. But to ensure VLAN setting will not impact the normal monitoring,

it’s better to use the Ethernet electrical port labeled “Data2/NM” as the

network management monitoring interface.

2.3.6 Power Switch and Power Socket

Two power options are available, ~220V AC or -48V DC. It should be

specified at the time of purchase.

Installation

3.1 E1/T1 connections

AN-TDM-IP-1E1-A supports 1 E1-120Ω/T1-100Ω balanced interface and

AN-TDM-IP-2E1-A can support 2 E1-120Ω/T1-100Ω balanced interfaces. The

RJ-48C sockets are default for all the ports. Besides, it can also support 75Ω

non-balanced interface by the Dip switches on the rear panel and external impedance

converting cable.

E1/T1 interface provide RxTx、Tx Rx through NMS, and the loopback of

E1 channels can be set up independently. RxTx、Tx Rx loop back definition is

shown in Fig 3.1.-1:

Fig 3.1-1 E1/T1 loop back

RxTx can test E1/T1 connection cable, and Tx Rx is used to test the whole

circuit including AN-TDM-IP-1E1/2E1-A in the two ends and the link between them.
