Table 3-6: BTS GUI Login Procedure
n ActionStep
7 Type in the correct IP Port number (normally 9216) if not correctly displayed in the IP Port box.
8 Click on Ping.
– If the connection is successful, the Ping Display window shows text similar to the following:
Reply from 128 128.0.0.2: bytes=32 time=3ms TTL=255
– If there is no response the following is displayed:
128.0.0.2:9216:Timed out
If the MGLI fails to respond, reset and perform the ping process again. If the MGLI still fails to
respond, typical problems are shorted BNC to inter–frame cabling, open cables, crossed A and B
link cables, missing 50–Ohm terminators, or the MGLI itself.
9 Select the Multi-channel Preselector type from the Multi-channel Preselector drop–down list
(default is MPC) to a device corresponding to your BTS configuration, if required.
NOTE
“Use a Tower Top Amplifier” is not applicable to the SC4812T Lite.
10 Click on Login. (A BTS tab with the BTS and frame numbers is displayed.)
NOTE
S If an attempt is made to log into a BTS that is already logged on, all devices will be gray.
S There may be instances where the BTS initiates a log out due to a system error (i.e., a device
failure).
S If the MGLI is OOS–ROM (blue), it must be downloaded with RAM code before other devices
can be seen.
S If the MGLI is OOS–RAM (yellow), it must be enabled before other installed devices can be
seen.
