Figure 3 displays a screen shot of the IMA Group

Provisioning screen. Note the hotkeys described at

the bottom of the page – P for Previous group, N for

Next group, and E to Enter the group number.

NOTE

Any changes made in this menu must be made

while the group is provisioned to the Out of

Service – Unassigned Group Admin State.

The Group Admin State allows the user to place the

group In Service, Out of Service – Maintenance, or

Out of Service – Unassigned. While In Service, the

IMA group will pass data and send alarms to the SCU.

If the group is placed into Out of Service –

Maintenance, it will continue to pass data but will not

send alarms to the SCU. If the IMA Group is placed

in the Out of Service – Unassigned state, no data is

allowed to pass, and no alarms are sent to the SCU.

The Transmit Identifier is a number provisionable

between 1 and 255 that is transmitted in the ICP

Header and is IMA Group specific. The terminating

IMA device at the other end of the IMA circuit

accepts the Transmit Identifier that is initially

received. The accepted Transmit Identifier is stored,

and all other received transmit identifiers are validated

against the stored value. The stored value remains

until the IMA Group is disabled and re-enabled with a

different Transmit Identifier.

The Transmit Frame Length is the number of cells

transmitted in each IMA frame. This number is

provisionable on ADTRAN equipment but may not be

on other vendors’ equipment. The Transmit Frame

Length must match on both ends of the circuit. The

factory default frame length is set to 128 cells.

The Minimum Active IMA Links option corresponds

to the number of properly working IMA Links needed

for the IMA status to be Operational. This means that

if the Minimum Active Links option is set for three,

and two IMA links are up, the IMA Group will not

operate properly, and no data can be passed. This

option should only be set above one if the IMA Group

should fail after the loss of a certain number of IMA

links. This option may be provisionable on the

connected IMA equipment, but does not have to be set

to match the setting on the Total Access Quad IMA

Access Module.

The Maximum Link Delay refers to the maximum

amount of delay (in milliseconds) allowed between

the arrival of two consecutively numbered IMA

frames. The maximum link delay may be set between

25 and 100 ms. This option does not have to match

the connected IMA equipment.
