• Line Build Out - pulse shape of the T1 analog interface:
♦ Line Loss (pulse shape of the T1 analog interface): Line CI code, as defined
by ANSI T1.403 Annex H

3.3.3.2.3 Configuring SHDSL WAN Interface
The SHDSL WAN interface can be set up using a variety of protocol configurations. The
WAN connection must contain a physical interface specification (SHDSL pairs and
grouping information) and one or more Layer-2 protocols (PPPoE, PPPoA, RFC 2684
ETHoA, or IPoA). This configuration must match the network setup provided by your
Internet Service Provider (ISP).
