Mitel LINE INTERFACE MODULE DATASHEET

DATA SHEET

Provides Teleworkers with Local Emergency Access

Mitel®Line Interface Module ensures mission-critical enterprises always have voice
communications. It also enables remote workers to have localized calling and emergency
services as well as failover capability in the event of a network failure.

Mitel Teleworker Solution Enhancement

Line Interface Module is a discreet component that
plugs into the back of your Mitel 5224, 5235, 5324,
5330, 5340 or 5360 IP Phones for local access,
emergency dialing and guaranteed survivability.
With it, voice communication automatically and
transparently defaults to a public switched telephone
network (PSTN) analog line if IP service is disrupted,
allowing users to continue to make and receive
calls. It works as a convenient solution that

enables remote workers and teleworkers to have
local calling capability and access to local emergency
services. If something should happen to the network,
DSL services or even the local router, teleworkers still
have uninterrupted access to voice communications.
Line Interface Module is, in essence, a low-cost
disaster recovery solution for converged,
mission-critical environments of any kind.

Power Configuration

Line Interface Module utilizes Power over Ethernet
(IEEE 802.3af). Local 24 V DC power adapter for the
5220 and 5224 IP Phones or 48 V DC Ethernet power
adapter (purchased separately) for the 5235, 5324, 5330,
5340, and 5360 IP Phones is recommended for
teleworker or remote use.
