Chapter 1. Introduction I. Features The SHDSL NTU offers two different ways to connect customers to highspeed TDM services with two G.703 E1 interfaces (balance 120 Ohm RJ45 jack or unbalance 75 Ohm dual BNCs). The G.703 interface will carry data at N*64kbps rates (where n=1~32). The SHDSL NTU can be configured and managed via EOC, or menu-driven VT100 compatible Asynchronous Terminal Interface, either locally or remotely.
