5. Installing the Remote Link
5.1 Introduction
The EAC-2100 normally will be equipped with an Ericsson T18D handset for remote
link access. Use of the T18D for remote access will require that the local TIA-136
system have digital data service to the handset enabled. This is in addition to the
normally available data originate feature available in TIA -136 systems.
An alternative interface may be provided via the PCMCIA interface on the front of the
controller card. In this case, a PCMCIA card that has wireless radio capability (either
analog or digital) may be plugged into this slot. The PCMCIA front connector will
then be used to interface with a compatible handset or mobile.
The PCMCIA slot may also be used with a wire-line type of PCMCIA modem for
connection to a telephone line.
When data-terminate capability is enabled in the cellular switch, the T18D handset in
the EAC-2100 may be dialed using a remote terminal and compatible modem.
Once the remote link is established, the interface with the system is exactly like that on
the local link, but possibly at a different baud rate. If both links are up, characters typed
on either terminal are echoed to both, along with the resulting EAC-2100 output. This
makes it possible for an experienced operator to exercise the system remotely while
someone watches locally, or for the two to exercise the system together.
Procedures. Establishing the remote link involves:
• Setting up service to the handset
• Programming the handset
• Checking out the handset
• Testing the remote link
