The IP5122-SDC supports a feature key, programmed as a Analog
Central Office (ACO) key, for accessing a Local Analog Loop-Start Line
(CO-Line) connected the station. The ACO key is assigned on one of the
Flexible Keys. Only one ACO key can be assigned to a station as this key
accesses the CO-line connected directly to that telephone (not switched
through the IPedge or VIPedge system). By default the IP5122-SDC will
have the ACO key assigned to FB10. If there is no CO-Line
connected to the phone, FB10 will be solid red.
An example application is shown in
York can dial a trunk access or LCR access code to dial out, through the
IP network, on the Los Angeles office trunks. However, an emergency call
made from the New York station, using a trunk access or LCR code,
would go to a Los Angeles area emergency call center. If the New York
station user selects the local CO line button the call will go through the
local N.Y. central office to a local emergency call center. Also, if the link to
the L.A. office is down, the N.Y. station can still use the local CO line to
make and receive calls, provided the IP5122-SDC has power. The
IP5122-SDC can be powered by PoE or a local AC Adapter.
IP Network
By pressing the ACO key, this IP5122-SDC connects to the Local CO
Trunk connected to this IPT Telephone. The station user can select the
ACO key to access the co-line or another key, to access the IPedge/
VIPedge system.
