RAM code downloading requires a few minutes. After the download

starts, the non–GLI device being loaded changes to OOS–ROM (blue). If

the download is completed successfully, the non–GLI device changes to

OOS–RAM (yellow).

The devices to be loaded with RAM code and data are:

S Master Group Line Interface (MGLI2)

S Redundant GLI (GLI2)

S Clock Syncronization Module (CSM) (Only if new revision code must

be loaded)

S Multi Channel CDMA (MCC24 or MCC8E) card

S Broadband Transceiver (BBX2)

S RFDS Test Subscriber Interface Card (TSIC), if equipped

The MGLI must be successfully downloaded with RAM

code and data, and in INS (green) status before

downloading any other device. The RAM code download

process for an MGLI automatically downloads data and

then enables the MGLI.

IMPORTANT

Verify GLI ROM Code Loads

Devices should not be loaded with RAM code which is for a different

system release than the ROM code with which they are loaded. Before

downloading RAM code and data to the processor cards, follow the

procedure in Table 3-13 to verify the GLI devices are loaded with the

correct ROM code for the system release used by the BSS.

Table 3-13: Verify GLI ROM Code Loads

Step Action

1 If it has not already been done, start a GUI LMF session and log into the BTS ( refer to Table 3-7).

2 Select all GLI devices by clicking on them, and select Device > Status from the menu bar.

3 In the status report window which opens, note the number in the ROM Ver column for each GLI2.

S The system release number will be the first two decimal divisions of the number; for example, the

number 2.15.0.0.3 would be for System Release 2.15, and 2.9.2.2.34 would be for System Release

2.9.

4 If the ROM code loaded in the GLIs is not for the correct system release, log out of the BTS,

disconnect the CDMA LMF computer, reconnect the span lines as described in Table 5-7, and have the

CBSC download the correct ROM code version to the BTS devices.

5 When the GLIs have the correct ROM load for the system release being used, be sure the span lines

are disabled as outlined in Table 3-4 and proceed to downloading RAM code and data.
