Total Access Deployment Guidelines for HDSL2
The ADTRAN Total Access 3000/3010 system is designed to deliver HDSL2-based
services over loops that are in compliance with the Carrier Service Area (CSA)
guidelines listed below:
• All loops must be non-loaded.
• The maximum loop length, including bridge tap, for 26 AWG cable is 9 kft.
• The maximum loop length, including bridge tap, for 24 AWG cable is 12 kft.
• Any single bridged tap is limited to 2 kft.
• Total bridged tap is limited to 2.5 kft.
• The total length of multi-gauge cable containing 26 AWG cable must not exceed
the following:
12 – {(3*L
26
) / (9 – L
BTAP
(in kft.)}
L
26
= Total length of 26 AWG cable excluding bridge taps (in kft.)
L
BTAP
= Total length of all bridge taps (in kft.).
