4-19Internal Calling/Uniform Dialling Plan. Station to station and station to group calls can bemade across the network link without having to dial an access code for a call within the net-work. LCR can also be programmed to route calls across a network link to access localtrunks in another networked system.Centralised Voice Mail with Message Waiting Lights. This feature will operate only withSVMi-8 or SVMi-4 voicemail systems. Users in one node can call forward (CFNR, CFB andCFU) to the voice mail group in a different switch and messages left in that switch will be in-dicated on the VMSG key in the originating switch. Messages can be returned to voice mailby pressing the VMSG key.Message Key and Light. The MSG key on a station can be activated across a network nodeso that they can reply to messages sent from the other system by pressing the key. The keyworks for Message and VMAA groups (third part VM systems should be tested prior to instal-lation).Group Overflow to Network Node. UCD groups can overflow to other network nodes. Inprogramming, the Next Port for overflow is set as a network station or group. When overflowoccurs, the original group stops ringing.UCD Final Destination. UCD groups can be assigned network stations or groups as the Fi-nal Destination.Trunk Ring Across Network Nodes. Trunk lines can be set to ring a network station orgroup in MMC 406.Paging Across Network Nodes. Paging to remote nodes can be achieved by assigning aNetwork Page key (MMC 722/723) or code (MMC 724). The page zone is the network linknumber assigned in MMC 820 (01−49) followed by the page group. For example, a key pro-grammed as NPG051 will page the node assigned to Link 05 and access internal paginggroup 1.VT Key Across Network Nodes. If a centralised SVM system is used, the VT key will workfor local voicemail and remote stations, local stations and remote voicemail, and remotevoicemail and remote stations.Enhanced Centralised Voice Mail. Display and soft keys can work on remote stations. Themessage count is displayed, and when a mailbox is accessed the display shows optionsFWD, DEL, REPLY, etc.BLF Across Network Nodes. A Network Station (NS) key can be programmed in the sameway as a DS key. With a station extender, it will flash when the station rings and steady whenit is busy. Pressing the key rings the station, and ringing calls can be picked up from the sta-tion when the key flashes. Holding calls and Call Park and Page are also supported.NOTE: For direct pickup, DSS KEY DPU in MMC 210 must be set ON. The BLF feature is only avail-able when systems are networked via the Internet Protocol and not Q-SIG, and is restricted to a maxi-mum of 400 stations per node.
