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.
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).
