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
MGLI MMI port (see Figure 5-1).
2 Start an MMI communication session with MGLI by using the Windows desktop shortcut icon (see
Table 3-3 on page 3-11).
NOTE
The LMF program must not be running when a Hyperterminal session is started if COM1 is being
used for the MMI session.
3
Verify the span parameter settings for frame format, equalization, and linkspeed for the span to be used
by entering the following at the
GLI3> prompt:
config ni current
The system will respond with a display similar to the following:
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)
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
S Defaults for span equalization are 0–131 feet for T1/J1 spans and 120 Ohm for E1.
S Default linkspeed is 56K for T1 D4 AMI spans and 64K for all other types.
S There is no need to change from defaults unless the provisioned span configuration requires it.
4 The span parameter settings in the GLI must match those provisioned in the OMC–R database for the
BTS. If they do not, proceed to Table 5-5 to change the span parameter settings.
5 Repeat steps 1 through 4 for all remaining GLIs.
6 Exit the GLI MMI session and HyperTerminal connection by selecting File from the connection
window menu bar, and then Exit from the drop–down menu.
