system. The SL2100 will then find the destination IP Address by searching Program 10-27 for the
destination IP Address for the given Node ID number.
Quantity of Voice Paths Available
The quantity of voice calls that can be made at any one time are dependent on various factors.
VOIPDB Resource - A free VOIPDB resource must be available at each SL2100 system.
Program 10-19 - The mode of each VOIPDB resource can be configured, modes 0 (ICM/Trunk) or 3
(NTW) can be used by AspireNet calls.
IP Network Bandwidth Restrictions - These limitations are beyond the scope of the SL2100 . If there is
not enough bandwidth available the call can not be maintained.
5.1.2 Multi-Site Networking Example
Multi-Site Networking is a network of three or more SL2100 systems. The network can consist of either
ISDN or IP network connections.
The example below shows three SL2100 systems, each has a VOIPDB Blade installed. The VOIPDB
Blades are connected to a hub via a standard LAN patch cable.
SL2100 A has extension numbers in the range 200-299, SL2100 B has 300-399, and SL2100 C has
400- 499.
