BCWARN IP and PBX Extension's Specification Jeremy Cohoe VA7NSA 15-DEC-2005 This document has three variables, x y z where X is the location identifier Y is the side identifier Z is the extension or IP number The IP Spec should match the Extensions spec as closely as possible For example, 10.x.y.z for an IP, and xyzzz for an extension There are two conventions to be decided and agreed upon. 1. Extensions should be no longer than 3 digits, plus a 1 digit location code. Max dialed digits is 4. Example: [x][yyy] Where x is the location identifier Where yyy is the site and extension suffix 2. Extensions should be no longer than 3 digits, plus a 1 digit location code and a 1 digit site code. Max dialed digits is 5 [x][y][zzz] Where x is the location identifier Where y is the site identifier Where zzz is the local extension A publicly available directory should be available, listing x,y, and zzz. Where x is the location identifier, y is the site identifier, and zzz is the local extenion For example, x (location identifier) would be 1, 2, or 3. 1 would be sites traditionally served directly by the root radio, SFU 2 would be sites traditionally served from a repeater, such as a site on Saltspring Island 3 would be sites traditionally served from a repeater, such as a site on Sumas Mountain For y (site identifier), will range from 1 to 9. (Or 1 to 0 depending) Will this be enough? That's 9 or 10 sites(y) max per location(x) Examples of extensions follow 12111 1xxxx, start off by calling a user connected directly to SFU x2xxx dial the site xx111 dial the extension Local PBX's should be configured so that 3 digit calls get routed to the appropriate local extension. Local PBX's should be configured so that 4 digit calls get routed to the appropriate site and extension Local PBX's should be configured so that 5 digit calls get routed to the appropriate location, site, and extension Examples: All calls routed directly through Seymour are 1 All calls routed directly through SFU are 2 All calls routed directly through Surrey Centre are 3 VECTOR's site code is 1 VECTOR Mobile Command code is 2 NWARC's site code is 1 BARC's site code is 2 Coquitlam's site code is 1 So, to dial YYY at Coquitlam FROM New Westminster a user would dia 31yyy To dial YYY at New Westminster FROM Coquitlam a user would dia 21yyy How does a node that changes it's router (IE if the Salt Spring Island node changes from connecting to SFU to connecting to Seymour) effect the dialing pattern? And what if the Surrey repeater connects through the repeater at NWARC? All nodes connecting to Surrey will remain the same?
