Avaya 6424D+M - TABLE 11-1. Power Supply Distance Limits

BRI: DEFINITY GENERIC 2 WITH UNIVERSAL MODULES 11-3
● 346A bulk power supply —
Four 10-watt outputs of -48 VDC each; located in the satellite closet
and not limited to powering BRI terminals. The 346A is switch-selectable and can also supply two
outputs of 20 watts each.
● 329A
— One 25-watt output at -48 VDC.
It can be located in the satellite closet or at the
workstation.
Table 11-1, Power Supply Distance Limits, shows power consumption and distance limits for the 7500
ISDN BRI voice terminals and one adjunct, either the S101A, S201A, or 500A. These distances are
conservative and are valid for both 40V and 48V power supplies.
