data catalogue services which are symmetrical i.e. N3-2-26, n3-2-27, N3-2-28 & N3-2-29. for the
other Hosted Voice services the CFUR (Call Forwarding Un-Registered) capability allows an
alternative number (mobile or PSTN number) to be designated to which calls will be diverted should
a failure of the access circuit or CPE cause the handset to go ‘Un-Registered’
CFUR can also be used as a ‘belt & braces’ option for those HVS Services with a secondary Voice
Connection

Survivable Remote Site Telephony (SRST)
N3 Voice Service
SRST is a licensed product which runs on a CISCO router enabling that router to take on limited
functionality of a Call Manager in the failure scenario where the connection to the N3 Network has
been lost.
SRST on it’s own allows internal calls within that site to be made to and from all handsets which
have been designated SRST handsets.
To provide resilience the SRST router is hosted on a free LAN port on the Customer’s or N3
supplied LAN switch.
Survivable Remote Site Telephony (SRST) with Local PSTN Access
For sites with existing PSTN connections by upgrading the SRST router hardware to include as
appropriate a BRI or PRI card (for ISDN2/30 connection) the router can be configured in such
away that should the site become isolated from N3 Network, calls could continue to be made and
receive via the local PSTN connection.
In addition those handsets not included in the list of designated SRST handsets could have CFUR
(Call Forwarding Un-Registered) to point either to a PSTN or mobile number or alternatively to
one of the SRST enabled handsets extension number.
