Touchstone Telephony Release 5 Standard 1.2 Mar 2007

Telephony Requirements

Each telephone line supports copper wire loop lengths of up to 128¾,

equivalent to 1500 feet of 26 AWG (American Wire Gauge) copper

wire loop. The loop length includes the cable between the Telephony

Modem and punch-down block, subscriber premises wiring, and exten-

sion cables used with subscriber CPE.

The Telephony Modem uses a cable with RJ-21X connectors to the

punch-down block.

Network Requirements

If the Telephony Modem is to provide data service for subscribers, a

100BaseT Ethernet connection (usually a hub or switch) must be avail-

able.

Note: When most or all lines are off-hook, data services may be

impacted due to lack of bandwidth.

For best results, the RF connection should use RJ-6 coaxial cable, cut

to the minimum practical length to minimize losses. The HFC network

must be DOCSIS 2.0 compatible.
