works in conjunction with Add Time to increase bandwidth, if it
is available.
Lower Threshold
Defines the percentage of available bandwidth that must be in use
to maintain bandwidth levels. If the bandwidth in use falls below
this level for longer than Drop Time, a channel drops. A very high
Drop Threshold increases the number of channels used, which
could increase costs.
Add Time
Defines the length of time that bandwidth must remain above
Raise Threshold before adding a channel.
Drop Time
Defines the length of time that bandwidth must remain below
Lower Threshold before dropping a channel.
Available Channels
Sets the number of available channels to be used in an AO/DI call.
From the Protocols Tab, you can also define the BONDING specifica-
tions using the following options:
Type
Defines the type of equipment used in a call. Set to ADTRAN Only
when originating BONDING calls to ADTRAN legacy ISU
equipment; otherwise, set this field to Multi-Vendor.
TXINIT
Specifies the length of time (in seconds) that the originating unit
attempts to detect the Async BONDING negotiating pattern from
the answering unit before determining Async BONDING has
failed.
TXFA
Specifies the length of time (in seconds) both units attempt to de-
tect the Async BONDING frame pattern when connecting a call
before determining Async BONDING has failed.
