Binding

When the RTN equipment accesses IMA services, configure bound channels in an ATM IMA group at the access node. One ATM IMA group corresponds to one ATM trunk port. Bind channels with the ATM trunk port and then enable the IMA group. The ATM trunk port can be bound with one or several E1 or Fractional E1 ports. In this interface, you can configure the bound paths of the ATM IMA.

Navigation Path

This user interface is applied to in the interface management and ATM service management. The navigation path is as follows:

In the NE Explorer, select the NE and choose Configuration > Interface Management > ATM IMA Management from the Function Tree. Then, click the Binding tab.
In the NE Explorer, select the NE and choose Configuration > > ATM Service Management from the Function Tree. Then, click the Binding Path tab.

Buttons

Button	Description
Delete	Delete the redundant or idle IMA groups to release the resources. Select an IMA group. Click Delete. A dialog box is displayed, indicating that the operation may interrupt the services. Click OK. A dialog box is displayed, indicating that the operation is successful. Click Close. NOTE: The IMA Protocol Enable Status of the IMA group must be Disabled. NOTICE: If any service is configured and activated at the ATM Trunk port for the IMA group, deleting the IMA group may interrupt the services. Exercise caution for this.

Button

Description

Delete

Delete the redundant or idle IMA groups to release the resources.

Select an IMA group. Click Delete. A dialog box is displayed, indicating that the operation may interrupt the services. Click OK. A dialog box is displayed, indicating that the operation is successful. Click Close.

NOTE:

The IMA Protocol Enable Status of the IMA group must be Disabled.

NOTICE:

If any service is configured and activated at the ATM Trunk port for the IMA group, deleting the IMA group may interrupt the services. Exercise caution for this.

Parameters

**Table 1** Descriptions of the parameters for the binding
Field	Value	Description
VCTRUNK	Slot number - Board name - Sub-slot number - Sub-board name - Sub-board port number (Trunk number)	Displays the VCTRUNK. NOTE: When the MLPPP or CES services is configured or the DCN is enabled on the VCTRUNK, the VCTRUNK resources are occupied and thus the IMA group cannot be created. The VCTRUNK that is first added into the IMA group should be deleted at last.
Level	E1, Fractional E1	Displays the level of the bound path. E1: The entire E1 channel is used to transmit ATM IMA signals. Fractional E1: Certain 64 kbit/s timeslots of an channel/path are used to transmit ATM IMA signals. NOTE: Before selecting the Fractional E1, ensure that the serial port for the 64 kbit/s timeslot is created. When an E1or Fractional E1 port is bound with an IMA group, Port Mode should be set to Layer 2.
Direction	Bidirectional	Displays the direction of the bound path.
Optical Interface	Example: 4-CD1-1(SDH-1)	Displays the optical interface of the bound path.
Bound Path	Example: Slot-Board Name-(Bound path)	Displays the bound path.
Bound Path Count	Example: 4	Displays the number of bound paths. NOTE: The unidirectional bound path number is displayed. For example, if two E1 ports are bound, four bound paths are displayed.
Display in combination	Checked, Unchecked	If you do not check Display in combination, each parameter that is bound with timeslots, such as the level and direction, is displayed in Selected Bound Paths. Otherwise, the parameters are displayed in combination.
IMA Group Status	Example: Active	Displays the state of the IMA group.
Available Boards	Example:3-MD1	Displays or sets the available boards.
Configurable Ports	Example:3-MD1-1(TRUNK-1)	Displays or sets the configurable ports. NOTE: Only the E1 ports on the same processing board can be bound. When the member links of an IMA group are at the serial ports of the 64K level, there are the following restrictions: One serial port should be bound with a minimum of three 64K timeslots. The number of bound 64K timeslots should be the same for different serial ports. In one E1, only one serial port can be used as a member link of an IMA group.
Frame Mode	30, 31	Set the value of the frame mode. The frame modes of the local port and opposite port should be the same.
Optical Interface	Example:6-MP1-CD1-1(PORT-1)	Displays or sets the available optical interface.
Available Resources	Example:3-MD1-1(PORT-1)	Displays or sets the available resources.
Available Timeslots	Example:VC12-1	Displays or sets the available timeslots.
