ADSL/CDSL Circuit Protection
Asymmetric Digital Subscriber Lines (ADSL) and Consumer Digital Subscriber Lines
(CDSL) employ an asymmetic digital line technology (Figure 3-7). This technology
employs a transmission rate up to 6.144 Mbps from the Central Office Terminal (COT)
to the Remote Terminal (RT) and a 640 kbps transmission rate from the RT to the COT
at distances up to 12,000 feet. Currently ANSI T1.413 specifies a maximum ring
voltage of 103V
RMS
and a boosted battery of 60V
DC
, however this is subject to
change.
Protection Circuitry
In Figure 3-8, longitudinal protection was not used at either the ATU-C interface or the
ATU-R interface due to the absence of earth ground connections. In both instances,
metallic protection is accomplished using the P3500SC SIDACtor and F1250T
TeleLink. For ATU
s not isolated from earth ground, please reference the HDSL
protection topology.
Component Selection
The P3500SC SIDACtor and F1250T TeleLink were chosen to protect the ATU
s
because both components meet GR 1089 surge immunity requirements without the
use of additional series resistance. Furthermore, although the P3100 series SIDACtor
may be used to meet current ANSI specifications, Teccor recommends the P3500
series to ensure compliance with a 150V
RMS
ringing signal superimposed on a
105V
DC
boosted battery.
