Configuring the GEIUT/GOIUT

This describes how to add a GEIUT/GOIUT in the GMPS/GEPS/GTCS and configure its attributes in BM/TC separated mode. The GEIUT and GOIUT are responsible for the E1/T1 transmission and STM-1 transmission between the GMPS/GEPS and the GTCS.

Prerequisite

The GMPS/GEPS/GTCS has idle slots to hold the GEIUT/GOIUT.

NOTE:

If the GEIUT/GOIUT in independent mode is configured in the GTCS, the corresponding active/standby slots cannot be configured with any board.

Preparation

Table 1 Example of the data negotiated and planned for configuring a GEIUT

Parameter	Example	Source
Board Type	GEIUT	BSC internal planning
Work Mode	E1	BSC internal planning
Active/Standby Mode	Selected	BSC internal planning
Load Key	Server	BSC internal planning
Frame Format	DOUBLE_FRAME	Negotiation with the peer

Table 2 Example of the data negotiated and planned for configuring the GOIUT

Parameter	Example	Source
Board Type	GOIUT	BSC internal planning
Work Mode	E1	BSC internal planning
Active/Standby Mode	Selected	BSC internal planning
Load Key	Server	BSC internal planning
Tributary Numbering	HuaWei mode	Negotiation with the peer
TX J0 Byte	MGW SDH DEFAULT (character string)	Negotiation with the peer
Expect RX J0 Byte	MGW SDH DEFAULT (character string)	Negotiation with the peer
TX J1 Byte	MGW SDH DEFAULT (character string)	Negotiation with the peer
Expect RX J1 Byte	MGW SDH DEFAULT (character string)	Negotiation with the peer
TX J2 Byte	MGW SDH DEFAULT (character string)	Negotiation with the peer
Expect RX J2 Byte	MGW SDH DEFAULT (character string)	Negotiation with the peer
TX Frame Format	CRC4_MULTIFRAME	Negotiation with the peer
RX Frame Format	CRC4_MULTIFRAME	Negotiation with the peer

NOTE:

When the parameter Optical Interface Standard is set to SONET, you must configure the following parameters: High Order Path 1 TX J1 Byte, High Order Path 1 Expect RX J1 Byte, High Order Path 2 TX J1 Byte, High Order Path 2 Expect RX J1 Byte, High Order Path 3 TX J1 Byte, and High Order Path 3 Expect RX J1 Byte.

The procedures for configuring the GEIUT and GOIUT are the same. The following procedure takes how to add a pair of active and standby GEIUTs in the GTCS as an example.

Procedure

1. On the BSC6000 Local Maintenance Terminal, click the BSC Device Panel tab. Select the number of the cabinet where the GTCS is located from the Current Cabinet drop-down list.
2. Right-click an idle slot among slots 14-17 holding the GTCS, and then choose Add Board from the shortcut menu. A dialog box is displayed, as shown in Figure 1.

3. Set FuncType to Ater interface board, and set Board Type to GEIUT. Then, set other parameters by referring to Table 1.
4. Click Finish. The addition of the GEIUT is complete.
5. Right-click GEIUT, and then choose Configure Board Attributes from the shortcut menu. A dialog box is displayed, as shown in Figure 2.

6. Set Load Key, and then click Next. A dialog box is displayed, as shown in Figure 3.

7. Set the port attributes of the GEIUT by referring to Table 1.
8. Click Finish. The configuration of the GEIUT is complete.
