Meridian 1 Remote Services
Line-Side E1 Interface
Overview
Meridian 1 Remote Services products allow businesses to distribute a single Meridian 1 system throughout
their campus, across town or across the continent while maintaining the convenience and economy of
centralised resources and control. Line-Side E1 is a complimentary addition to the Meridian 1 Remote Services
portfolio, which includes ISDN Networking, Fibre Remote and Carrier Remote. The Line-Side E1 interface card
provides a cost-effective connection between E1 compatible equipment (ie such as voice mail systems,
integrated voice response units) and a Meridian 1 system. Used in these kinds of applications, the Line-Side E1
interface eliminates the need for expensive channel bank equipment.
Customer Profile
• Businesses seeking “line side” functionality to
support E1 compatible devices via a direct
connection to the Meridian 1
• Customers intending to connect IVR equipment to
the Meridian 1 for contact centre applications
Typical Applications
An example where Line-Side E1 could be an ideal
solution is with E1 compatible voice response units
such as an IVR system. Using Line-side E1, Meridian 1
can send a call directly to the IVR system and
because the Line-Side E1 card supports 2500-type
functionality, the IVR system can send the call back
to the Meridian 1 for further handling. This is a
significant improvement over previous alternatives.
Previously, if a digital “trunk-side” connection was
used to the IVR system, the IVR system could not
transfer the call back to the Meridian 1. Analogue
ports and channel bank equipment would have to
be deployed for line-side capability – a much more
expensive solution.
Key Points
• The Line-Side E1 interface is appropriate for any
application where both E1 connectivity and “line
side” functionality is required. It provides a direct
connection between the Meridian 1 and third
party E1 compatible equipment. This results in a
more robust, reliable and cost-effective
connection without the need for channel bank
equipment
• For connecting to IVR equipment, Line-Side E1
interfaces simplifies system configuration
resulting in reduced installation time and easier
maintenance of both the Meridian 1 and the IVR
equipment
Features and Benefits
The Line-Side E1 interface is an Intelligent Peripheral
Equipment (IPE) line card that is supported on
Meridian 1 Option 11 through 81C systems.
Line-Side E1 emulates an analogue line card to
Meridian 1 X11 software and requires two card slots
within the IPE (ie dual width card) to support 32 E1
ports. With full analogue line card functionality in
software, these Line-Side interfaces can provide
2500-type telephone set functionality (eg hook flash,
ring back tones from the Meridian 1). This “line-side”
functionality is crucial when used with equipment
such as voice mail systems, integrated voice
response units and trading turrets (used in stock
markets).
The Line-Side E1 interface is compatible with public
or private CEPT type carrier facilities.
Using Channel Associated A/B signalling,
it supports CRC-4 or FAS only framing formats as
well as AMI or HDB3 coding.
