Nailed MPP connections
A Nailed/MPP connection is a permanent connection that can add switched
channels for increased bandwidth. A Nailed/MPP connection is established when
its nailed or switched channels are connected end-to-end.
Switched channels are added to or subtracted from the Nailed/MPP connection as
required by the DBA parameters of either the far-end or near-end Connection
profile. If the two sides of a connection disagree on the number of channels
needed for a connection, the side requesting the greater number prevails.
Calculations on the required number of channels are made by each side based on
the traffic received at that side.
The maximum number of channels for the Nailed/MPP connection is either the
Max Ch Count or the number of nailed channels in the specified group,
whichever is greater. If a nailed channel fails, the Pipeline replaces that channel
with a switched channel, even if the call is online with more than the minimum
number of channels.
To configure a nailed MPP connection, first configure a regular MP+ connection
(see “Example MP+ configuration” on page 1-19). Then follow these steps:
1
Open the Telco Options submenu of the Connection profile.
2
Specify the Nailed/Mpp call type.
For example:
Call Type=Nailed/Mpp
3
Specify the group number of the nailed channels. (For a discussion of group
numbers, see “Nailed groups” on page 1-3.)
For example:
Group=1,2
4
Specify that the Pipeline is the designated caller for the switched part of the
connection.
For example:
AnsOrig=Call Only
FT1 Caller=Yes
5
Close and save the profile.
