A TIE line is a privately leased communication line between two or more PBXs, which provides cost effective communications between company members at different locations. A maximum of 32 TIE Line Routing and Modification Tables can be programmed. It is necessary to make unified tables with all PBXs at different locations in a TIE line network in order to identify the CO line route to be used when an extension makes or receives a TIE line call. There are two types of routing methods: the Extension Number Method, where all extensions in the network are given a unique extension number; and the PBX Code Method, where each PBX is given a unique code, which is dialed before the extension number to call an extension at another PBX. Two priority sets (from a total of 8) are displayed at a time. To display other priority sets, click the applicable tab. Using a private network, up to 8 PBXs can share one VPS (centralized VM) connected to another PBX. This VPS can provide voice mail for extensions attached to any of the PBXs in the network. Only extension numbers of 4 digits or less, using the Extension Number Method, are supported.
Own PBX Code
Specifies the PBX code of the local PBX, when using PBX Code Method numbering on a TIE line network. If this cell is left empty, the Extension Number Method is used.
Settings related to the transmission of extension BLF (Busy Line Field) data or Message Waiting notifications over a network of PBXs can be programmed. Extension BLF data is used to show the status of a monitored extension attached to another PBX on a Network DSS (NDSS) button. Network Message Waiting notifications are used for the Centralized VM feature, and a VPS can send notifications to extensions connected to any PBX in the network.
Network Data Transmission for Centralized Operator Feature—Network PBX ID
Specifies the Network ID of the PBX, for Network Direct Station Selection (NDSS). This parameter must be set in correspondence with the Network IDs assigned to other PBXs in the network. Network IDs 1-8 can only be assigned to one PBX each within a network. Assigning the same Network ID to two PBXs will cause network data transmission problems. Changing this value in Interactive mode will automatically clear any NDSS Link Data.
Default
0
Value Range
0: The PBX retransmits BLF data sent by other PBXs. 1: The PBX receives BLF data sent by other PBXs. 2–8: The PBX transmits BLF data over the network.
This screen allows network operators to be programmed. A network operator is an extension at a remote PBX that will monitor other PBX extensions using Network Direct Station Selection (NDSS). The settings on this screen should be programmed at the PBX that is to be monitored (Network Data Transmission for Centralized Operator Feature—Network PBX ID 2–8). Up to 8 network operators can be programmed.
Extensions at up to 7 other PBXs that will be monitored using Network Direct Station Selection (NDSS) can be registered. A maximum of 250 extensions can be registered. To create an NDSS button to monitor an extension, the extension must be registered here first. To clear NDSS link data, click the NDSS Clear button. Note that the parameters on this screen can only be set when the Network Data Transmission for Centralized Operator Feature—Network PBX ID is set to 1 in the 2.15.2 [9-2] Network Data Transmission screen.
Network Extension No.
Specifies the number of the remote extension (attached to another PBX) that will be monitored. The number input here can use either Extension Number Method or PBX Code Method.
