The Opera System may be expanded by connecting one or more “slave” racks, locally on the
LAN or remotely and using VoIP networking. The additional racks act as Slaves to the original
Master rack. All interfaces to the public network must be on the Master system; the Slaves can
only break out to the public network via the Master.
The maximum capacity of the Master and Slave racks combined is 60 channels (ISDN or SIP
trunks) to the public network and 240 users.
Each Slave has eight analogue a/b fixed extensions and three expansion slots. The three
expansion slots may be fitted with any combination of 8-UPN and 8-a/b FXS cards. All devices
connected at the expansion Slave racks must register as IP users on the Master system.
6.1. Assign IP Registration names and PINs on the
Master system for all Slave extension users
Log in to the Master system and go to the IP Phone Registration page and assign IP Registration Names
and IP Registration PINs for all users on the Slave systems.
In this example User Numbers 11, 12, 13, 15, 16 and 17 are assigned IP registration names IP101,
IP102, IP103, IP109, IP110 and IP111 respectively and removed from the Auto Discovery Pool on the
Master system, as indicated in the above screen shot from the IP Phone Registration page of the
Master. These IP registration names and PINs are then assigned to Users on Extension Registration
page of an associated Slave system.
