Meridian Data
The Meridian 1 PBX supports the switching of data through its TDM fabric.
This allows for several applications in which the voice network can be used
to transport data traffic. One such application would allow a communication
device at a given location, such as a PC, to access a server at another location.
Speeds up to 64Kbps can be achieved, as normal voice channels are assigned
to a data call for the duration of the session. Connectivity is achieved through
data modules which stand alone or exist as modules within digital sets. At the
PBX, several card options are supported, including the XDLC. As a result, a
highly reliable physical path is achieved through the Meridian 1 TDM fabric.
Please refer to
Features and Services
(553-3001-306) for more information.
The reliability of this data application relies on a highly robust layer 1, in this
case, the TDM fabric. The above NTP gives the following bit error rate as a
measure of this reliability:
•
In-house error rate <= 1 error x 10
-7
(1 error in 10Mbits)
•
Trunk error rate <=1 error x 10
-5
(1 error in 100Kbits)
In the case of IP Expansion, a packet loss of < 1% has been quoted to achieve
acceptable voice quality. This potentially means 1 error in 100 bits can be
fully tolerated for voice, but this is absolutely not suitable for Meridian 1 data
traffic. Therefore, Meridian 1 data can be transported to the same level of
reliability on an IP Expansion cabinet if the customer’s LAN can achieve 1
error in 100Kbits. Otherwise, it must be recognized that packet loss could
impact any application being transported. The zero bandwidth parameter for
the CHG IPR command in LD 117 must be set to NO to ensure that packet
loss due to synchronization of the IP link is avoided.
Network Requirements
When a Main and an IP Expansion Cabinet are connected by an Campus Data
Network, the quality of voice depends on the network. The network
requirements defined here must be met.
