135 Remote Office 9150
Survivable
Local Switching
Audio Compression
QoS Transitioning
Bridge Port
DiffServ and 802.1p QoS Support
Jitter Buffer Configuration
Multiple Subscriber Numbering (MSN) Support
Voice Activity Detection
If WAN connection lost to Meridian:
• Local station to station calls supported
• ISDN BRI Lines allow local outgoing and incoming
call for remote users
Station to station calls are switched locally saving
bandwidth to Meridian
Supports multiple codecs to maximise WAN
bandwidth
Dynamically switches calls from packet networks to
circuit-switched networks if voice quality degrades
The Bridge Port feature allows local PSTN calls
received or placed on the branch office’s ISDN BRI
phone numbers to be transferred, call-forward and/or
conference from the Remote Office 9150 branch office
to the Meridian 1 or Succession CSE 1000
communication system
802.1p Layer 2 QoS and DiffServ Layer 3 QoS
means improved IP performance. When installed on
a QoS-capable network, the Remote Office 9150
utilises these QoS features to ensure maximum IP
performance and voice quality over the IP network
Administrators can now minimise latency (delay) on
fast high-performance IP connections, or maximise
voice quality on IP connections that may need extra
buffering
Remote Office 9150’s support of MSN allows each
ISDN-BRI channel to have a separate DN (phone
number) from the CO. This means that each BRI line
can now have up to two phone numbers (one for each
B-channel). In some areas, this may be the only BRI
configuration supported
Voice Activity Detection (sometimes called silence
suppression) can dramatically reduce the amount of
IP traffic generated during a voice conversation. The
Voice Activity Detection feature allows one side (or
both) of a VoIP connection to stop sending traffic
when there is nobody speaking on that side
