Optimization Manual: Scope and Layout
Manual Scope and Layout
This document provides information pertaining to the optimization and
audit tests of Motorola SC 4812T Base Transceiver Subsystem (BTS)
equipment frames equipped with trunked high–power Power Amplifiers
(PAs) and their associated internal and external interfaces.
Also covered is Software Release R2.16.3.x which supports the
following versions of SC 4812T BTS sites:
– 1X Circuit BTS
– 1X Packet backhaul BTS
The 1X packet BTS has a packet backhaul network interface which is
provided via a pair of routers together with a GLI upgrade (GLI3) that
can handle voice (IS-95A/B, 1X) and data (IS-95B, 1X).
This BTS equipment is configured with all 1X cards (BBX–1X
andMCC1X) or a mix of 1X cards and non–1X cards (BBX2 and
MCC8E/24E). This configuration is compliant with all applicable
cdma2000 1X specifications. It provides the forward link and reverse
link RF functions to support 2G features and 3G-1X features (i.e., high
capacity voice and high bit rate data).
The 1X circuit BTS has a split backhaul (circuit/packet pipe) network
interface that can handle circuit based voice (IS-95A/B, 1X) and data
(IS-95B) as well as packet based data (1X).
Assumptions and Prerequisites
This document assumes the following prerequisites: The BTS frames
and cabling have been installed per the SC Product Family Frame
Mounting Guide manual, which covers the physical “bolt down” of all
SC series equipment frames, and the 1X SC 4812T BTS Hardware
Installation manual, which covers BTS specific cabling configurations.
In most applications the same test procedure is used for all equipment
variations. However, decision break points are provided throughout the
procedure when equipment specific tests are required.
NOTE
As the Code Division Multiple Access (CDMA) Local
Maintenance Facility (LMF) capability comes on–line,
applicable LMF based procedures will be incorporated.
Eventually, only the CDMA LMF platform will be supported as
the recommended customer method of interfacing with and
servicing the SC series BTS equipment.
We at Motorola Technical Information Products and Services have
strived to incorporate into this document the many suggestions and
inputs received from you, the customer, since the inception of the SC
product line. At the same time, we have tried to insure that the scope of
the document targets both the novice and expert site technician and
engineer with the information required to successfully perform the
task at hand.
