1.2 System Interfaces

System interfaces and associated signals for the RS8953B functional circuit

blocks are shown in Figure 1-8. Circuit blocks are described in sections 3 and 4,

and signals are defined in Table 2-2.

The single-pair version (RS8953SPBEPF and RS8953SPBEPJ) only supports

HDSL Channel 1. HDSL Channels 2 and 3 are not usable. Although only 1 HDSL

channel is usable, the internal registers are not changed from the 3 HDSL channel

versions. The single-pair versions (RS8953SPBEPF and RS8953SPBEPJ) only

supports HDSL Channel 1. HDSL Channels 2 and 3 are not usable. Although

only 1 HDSL channel is usable, the internal registers are not changed from the 3

HDSL channel versions. This means that the registers should be programmed

with the same value as if only HDSL channel 1 was used in a 3 channel version.

This allows the 3 channel version to be used for development, and without a

software change, a single-pair version used for production.
