The CRM-V-2 IP Flush Master with Display is an IP control room intercom intended for use in control and guard rooms. The station features a large high contrast display with adjustable backlight and up to 8 lines with 20 characters. The station has four direct access keys. Each key has a red and a green LED to show status.

The IP station supports open standards and is compatible with ICX-AlphaCom, IC-EDGE and iPBXs using SIP technology. When working in ICX-AlphaCom mode, the IP station supports special services only available using the CCoIP protocol, as employed by the AlphaCom server. Examples of services are emergency broadcast with volume override, CCTV integration, call priority, and AlphaNet multisite networking and event scripting.

Like all Zenitel stations, the CRM-V-2 features superb audio quality. This is enabled through a set of advanced technologies such as active noise filtering, acoustic echo cancellation, wide band audio codec, and high power audio outputs. The IP station has an integrated managed data switch providing advanced networking and security features. The integrated switch provides support for:

  • Protection from unwanted access
  • Quality of Service (QoS) by managing data traffic
  • Cost efficient installation by providing shared network connections

To provide maximum availability the station comes with advanced supervision functions. The station line test will detect if there is any faults in the network or station electronics. In addition the station supports tone test, testing the complete transmission path including microphone and speaker. The status of the stations is reported to AlphaWeb as well as to 3rd party management systems using SNMP, Syslog or OPC.

In IC-EDGE mode, the CRM-V-2 can be configured as the Edge Controller.
