Bogen paging example using FXS Pass Through feature.
The example below shows a Bogen PCM/ZPM Zone Paging unit at the Corporate site connected
through MultiVOIPs to amplifiers and speakers at each of two branch sites. Users at the corporate
site can page users at the Branch A and/or Branch B sites.
The FXS Pass Through feature allows an “always on” audio connection to exist between the
Corporate site and both Branch A and Branch B sites. The MultiVOIPs use of Silence Compression
means little or no bandwidth is used when not paging.

1. Preliminary planning: Determine the number of MultiVOIP gateways to be used for the paging network.
Assign a unique IP address and identifying number to each MultiVOIP. It is helpful to write this down
like below:

7. In the configuration / Voice/Fax screen, select one of the channels to be used for paging and click the
Auto Call Enable checkbox to enable the auto call feature. In the Phone Number field, enter x:y where
x equals the remote MultiVOIP identifying number and y equals the remote MultiVOIP Voice Channel
number. For example, on Corporate MultiVOIP channel 1 you would enter 2:1 to communicate with
Branch A voice channel 1. For best voice quality, configure the Voice Coder field to G.711 U-Law @ 64
kbps. For good voice quality requiring less bandwidth, configure the Voice Coder field to G.723.1 @ 6.3
kbps. You must use the same voice coder on channels that communicate with each other. Leave the
other fields set to defaults. Configure the other channels as needed and click Ok when finished.

8. Select Save Setup / Save and Reboot to save the configuration to the MultiVOIP.
9. Assuming a Bogen PCMZPM is located at Corporate, connect a RJ11 phone cord to channel 1 FXS/FXO
jack on the Corporate MultiVOIP. Connect the two wires on the other end of the phone cord to the Zone
A + and – leads on the PCMZPM. Connect another RJ11 phone cord between channel 2 FXS/FXO jack
and the Zone B + and – leads on the PCMZPM. A cord with an RJ11 plug on one end and tinned leads
on the other end is included for this purpose. Caution: set the PCMZPM output selector switch to Low
Power
10. At the Branch sites, connect a RJ11 phone cord between the MultiVOIP channel 1 FXS/FXO jack and
the TIP/RING leads of the speaker amplifier (TPU-15, for example). You cannot connect the speaker
directly to the MultiVOIP.
11. When all MultiVOIPs are powered on , a permanent audio connection will exist between Corporate
MultiVOIP channel 1 and Branch A MultiVOIP channel 1. Another permanent audio connection will
exist between Corporate MultiVOIP channel 2 and Branch B MultiVOIP channel 1. You can now make
pages From Corporate to Branch A and/or Branch B remote sites.
