Legacy Integration
14 – 28 ShoreTel, Inc.
System Requirements
The following are required on the ShoreTel 6.1 system, or on the legacy PBX to enable
the integration of the two systems:
• ShoreTel 6.1 system
— ShoreGear-T1 Voice Switch - The ShoreGear-T1 voice switch supports both T1
and PRI connections and includes an integrated CSU.
• Legacy PBX
— T1 or PRI card for the PBX
— Available card slot and capacity for the added trunks
— Required software or licenses to support the desired trunk interface
NOTE If PRI is used in the integration interface, the legacy PBX must emulate the CO
or support Network Side PRI.
Connection Cable
Special Considerations - Nortel PBX
When integrating with a Nortel Meridian PBX, a T1 connection must be used since the
legacy system does not support Network Side PRI.
Special Considerations - Avaya/Lucent PBX
Universal Dial Plan (UDP) Must be Active - This capability enables transparent dialing
between the Avaya/Lucent PBX and the ShoreTel 6.1 system. If this is not active, users
on the PBX will either have to dial a trunk access code to reach the users on the
ShoreTel 6.1 system, or configure forwarding from an extension in the legacy system to
the ShoreTel 6.1 extension using the trunk access code and the extension.
NOTE In some cases, this feature must be purchased separately from Avaya/Lucent.
