s, and PABX
’
s contain line cards that support various transmission
protocols such as ISDN, T1/E1, HDSL, and ADSL (Figure 3-24). PBXs also have
features such as a POTS (plain old telephone service) pull through which allows
stations to have outside line access in the event of power failure. All incoming lines to
the PBX are subject to environmental hazards such as lightning and power cross.
Protection Requirements
Branch exchange switches should be protected against over-voltages that can exceed
800V and surge currents of up to 100A.
Applicable Regulatory Requirements
FCC Part 68
UL 1459
UL 1950
Branch Exchange Reference Circuit
The following sections contain interface circuits used for protection of PBX line cards.
For POTS protection see pages 3-3 through 3-6.
For ADSL/CDSL protection see page 3-8
For HDSL protection see page 3-10.
For ISDN protection see page 3-12.
For T1/E1 protection see page 3-16.
For Station Protection see pages 3-19 through 3-23.
