Issue 8.01 UNIVERGE SV81002 - 1358 SV8100 NetLinkRestrictions All IP Trunks must be connected to the Primary System, Version 4000 (V4.01 or lower). The number of total ports depends on the Primary System. System ID (Program 51-01-02) must be unique for each system in a NetLink network. ACD/MIS can connect to the Primary (Main) site only. Only one Voice Mail can be installed in a NetLink network. In-Mail and VRS use the VMDB of the Primary (Main) site. APSU can be installed in the Secondary (Remote) System, however the NetLink time zonefollows the Primary (Main) System. Secondary systems must follow the primary CPU software settings for Mu-law/A-law withinthe country where the primary system is located. SV8100 NetLink connections are onlysupported within the same countries/areas. For example, the SV8100 can be connected viaNetLink between the US and Canada, however the SV8100 can not be connected viaNetLink with systems in other countries (e.g., Mexico or the U.K.). Synchronous Ringing via NetLink is not supported.NetLink Multi-SIP CarrierDescriptionThe Version 5000 enhancement enables multiple SIP Trunk carriers to be utilized when NetLink isconfigured.The operation of SIP Trunk is described as follows when an existing Version 4000 (V4.01 or lower)NetLink system is configured (refer to Figure 2-32 Example – Version 4000 or Earlier on page 2-1359). Ifthe secondary system calls for using a SIP Trunk a total of three DSPs are required. One DSP from thesecondary and two DSPs from the Primary system. Also, only 32 Register ID’s are available which areprogrammed in the Primary system.
