EAC-2000 MANUAL ADDENDUM FOR DIGITAL OPERATION

1.1 Introduction
This section of the manual describes EAC-2000 operation when it has TIA-136
digital-channel sets installed. An EAC-2000 may be ordered directly from the
factory with digital channel sets installed, or upgrade kits may be ordered to add
digital channel-set capability to an existing EAC-2000 installation.
digital-channel sets installed. An EAC-2000 may be ordered directly from the
factory with digital channel sets installed, or upgrade kits may be ordered to add
digital channel-set capability to an existing EAC-2000 installation.
In general the installation issues (isolation needs, channel selection, etc.) are
identical for either type of system and are covered in detail in the AMPS EAC-2000
manual. The differences between a TIA-136 equipped system and a standard
AMPS-only system will be covered in this section.
identical for either type of system and are covered in detail in the AMPS EAC-2000
manual. The differences between a TIA-136 equipped system and a standard
AMPS-only system will be covered in this section.
The hardware differences for a digital-equipped EAC-2000 are:
1.1.1 Controller Module
Controller Module 19-20001-1 is required for TIA-136 digital operation. If an
existing EAC-2000 installation has the older (analog only) 19-5598-1 Controller
Module installed, it must be replaced with the dual-mode 19-20001-1 Controller
Module. The 19-20001-1 module will process both analog and digital calls.

1.1.2 RF Module
The 19-20000-1 IS-136 RF Module is required for TIA-136 operation. It may be
placed in any card cage slot in place of the analog 19-5599-1 Cellular I.F. module
within the following constraints:
placed in any card cage slot in place of the analog 19-5599-1 Cellular I.F. module
within the following constraints:
•
A 19-20000-1 module must be placed in slot 5 for DCCH operation.
•
A 19-20000-1 module must be placed in slot 6 if dual-mode hand-in
operation is desired. If DCCH-only operation is implemented or if hand-
in of DTC calls is not required, then the analog 19-5599-1 Cellular I.F.
module may be left in slot 6.
operation is desired. If DCCH-only operation is implemented or if hand-
in of DTC calls is not required, then the analog 19-5599-1 Cellular I.F.
module may be left in slot 6.
•
If dual-mode (analog control channel as well as a DCCH channel)
operation is desired, then an analog 19-5599-1 module must be installed in
slot 1 for the analog control channel.
