An Avaya IP Office (AIPO) Station Port can be configured as a "Paging Speaker" to act as a Paging Port, but relatively few paging amplifiers are compatible with this configuration. For proper operation both must be true:
Paging Port must see 600-ohm load AND DC current must be not be blocked by any typical capacitive coupling.
The Viking AIB-1 (Audio Isolation Board) will facilitate connections to AIPO, and is required for use with the following Viking products:
FBI-1A
HF-3W
M2W
MTG-10
PA-2A
PA-30
PA-60
ZPI-4
These Viking products will interface DIRECTLY with AIPO "Paging Speaker" port:
FXI-1A
PI-1A
PA-15
PA-250
PP-250
Note: the Bogen WM1A is a suitable substitute for the AIB-1
