SC4812ET BTS Optimization/ATP — CDMA LMF

LMF to BTS Connection

The LMF is connected to the LAN A or B connector located on the left

side of the frame’s lower air intake grill, behind the LAN Cable Access

door (see Figure 3-4).

Table 3-6: LMF to BTS Connection

Step Action

1 To gain access to the connectors, open the LAN Cable Access door, then pull apart the Velcro tape

covering the BNC “T” connector and slide out the computer service tray, if desired (see Figure 3-4).

Connect the LMF to the LAN A BNC connector via PCMCIA Ethernet Adapter with an unshielded

twisted–pair (UTP) Adapter and 10BaseT/10Base2 converter (powered by an external AC/DC

transformer). If there is no login response, connect the LMF to the LAN B BNC connector. If there is

still no login response, see Table 6-1, Login Failure Troubleshooting Procedure.

NOTE

– Xircom Model PE3–10B2 or equivalent can also be used to interface the LMF Ethernet

connection to the frame connected to the PC parallel port, powered by an external AC/DC

transformer. In this case, the BNC cable must not exceed 91 cm (3 ft) in length.

* IMPORTANT

The LAN shield is isolated from chassis ground. The LAN shield (exposed portion of BNC connector)

must not touch the chassis during optimization.
