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
MGLI3 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 MGLI3/SGLI3 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)
S D D 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 0-40 m 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 MGLI3/SGLI3 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.
