“Analogue Intercom systems tend to be wired using twisted pair cable. Traditionally, 1-pair or 2-pair telephone type cable (typically to BT spec. CW1308) was used to connect each user intercom station to the central exchange equipment. However, with the advent of wired computer networks came an abundance of Cat5/6 cable which features 4 twisted pairs and which may also be used to provide connectivity for one or more analogue intercom user stations. The wired intercom provides very reliable service with very little down time due to network communications issues”
Analogue Intercom Systems Cable Length
With Analogue Systems be aware that line length can become an issue where the analogue system relies upon low level electrical (DC) signals to convey various conditions to the central equipment e.g. handset on/off hook, press-to-talk etc.,. In a typical analogue system, the maximum line length (central equipment to farthest intercom user station) may be expressed as a loop resistance figure e.g. 240 Ohms (120 Ohms per wire) – this equates to a line length of approx. 1.4km using 0.5mm diam. copper conductors.
IP Systems the alternative to Analogue Systems
An alternative to using Analogue Intercom Systems is to make use of IP Intercom Systems , designed to handle purely VoIP traffic or, as in the case of the AlphaCom XE-series equipment, to handle both VoIP and traditional analogue intercom user stations. In the case of analogue stations, connectivity with the central exchange remains a necessity, but outstations may be connected using an existing LAN.
The STENTOFON Pulse offers High Definition voice quality, simple installation and ease of use. The IP-based system works by utilizing an existing IP network infrastructure. It employs open standards including SIP, HTTP and XML, making it simple to integrate and expand with third-party systems.
Most IP or VoIP stations are powered by the network cable using PoE (Power Over Ethernet), PoE is supplied from a network switch providing an PoE output. Red Lion PoE switches
