Overview

This chapter contains information for installing your

E1 NTU. It includes application examples, cabling, and power-up information.

Application Examples

The E1 NTU acts as an interface between a High bit-rate Digital Subscriber Line (HDSL) network and the customer's equipment.

PBX

NTU

LAN

ROUTER

The E1 NTU is connected to the customer's equipment through one of the synchronous data ports (PORTs 1± 4) or the G.703 DTE port. It is connected to the network through the HDSL Network interface.

The E1 NTU normally operates in conjunction with a Line Termination Unit (LTU) that is installed in an ACCULINK Access Controller (AAC).

Some common applications for the E1 NTU are:

•Shared access to network-based services (Figure 2-1).

•Point-to-Point LAN interconnection (Figure 2-2).

•Fractional E1 network applications (Figure 2-3).
