BTS Site Span Configuration

Verification

Perform the procedure in Table 5-4 to verify the current Span Framing

Format and Line Build Out (LBO) parameters. ALL MGLI2/SGLI2

boards in all C–CCP shelves that terminate a T1/E1 span should be

verified.

Table 5-4: BTS Span Parameter Configuration

Step Action

1 Connect a serial cable from the LMF COM1 port (via null modem board) to the front panel of the

MGLI2 MMI port (see Figure 5-1).

2 Start an MMI communication session with CSM–1 by using the Windows desktop shortcut icon.

NOTE

The LMF program must not be running when a Hyperterminal session is started if COM1 is being

used for the MMI session.

3 Enter the following MMI command to display the current MGLI2/SGLI2 framing format and line

code configuration (in bold type):

span view <cr>

Observe a display similar to the options shown below:

COMMAND ACCEPTED: span view

The parameter in NVM is set to T1_2.

The frame format in flash is set to use T1_2.

Equalization:

Span A – Default (0–131 feet for T1/J1, 120 Ohm for E1)

Span B – Default (0–131 feet for T1/J1, 120 Ohm for E1)

Span C – Default (0–131 feet for T1/J1, 120 Ohm for E1)

SDD f lt (0 131 f t f T1/J1 120 Oh f E1)

Span D – Default (0–131 feet for T1/J1, 120 Ohm for E1)

Span E – Default (0–131 feet for T1/J1, 120 Ohm for E1)

Span F – Default (0–131 feet for T1/J1, 120 Ohm for E1)

Linkspeed: Default (56K for T1 D4 AMI, 64K otherwise)

Currently, the link is running at the default rate

The actual rate is 0

NOTE

Defaults for span equalization are 0–131 feet for T1/J1 spans and 120 Ohm for E1.

Default linkspeed is 56K for T1 D4 AMI spans and 64K for all other types.

There is no need to change from defaults unless the OMC–R/CBSC span configuration requires it.

If the current MGLI2/SGLI2 framing format and line code configuration does not display the correct

choice, proceed to Table 5-5.

4 Repeat steps 1 through 3 for all remaining GLIs.

5 Exit the GLI MMI session and HyperTerminal connection by selecting File from the connection

window menu bar, and then Exit from the dropdown menu.
