ISDN Circuit Protection
Integrated Services Digital Network (ISDN) circuits require protection at the NT1 U-
interface and at the Terminating Equipment (TE) and/or Terminating Adapter (TA) S/T
interface. Signal levels at the U interface are typically +/-2.5V, but with sealing currents
and Maintenance Loop Test (MLT) procedures, voltages approaching 150V
RMS
can
occur.
Protection Circuitry
In Figure 3-12, longitudinal protection was not used at either the U or the TA/TE
interface due to the absence of an earth to ground connection. At the U interface,
metallic protection is accomplished using the P2600SC SIDACtor and F1250T
TeleLink while the TA/TE interface uses the P0640SC SIDACtor and F1250T TeleLink.
For interfaces not isolated from earth ground, please reference the HDSL protection
topology.
Component Selection
The
“
SC
”
SIDACtors and F1250T TeleLink were chosen because these components
meet GR 1089 surge immunity requirements without the use of additional series
resistance. The P2600SC voltage rating was selected to ensure coordination with
MLT voltages that can approach 150V
RMS
. The voltage rating of the P0640SC was
selected to ensure coordination with varying signal voltages.
