Multiple Alarm Combiner (MAC) - slot 6
Slot 6 is wired only and not equipped.
Multiple Alarm Processor (MAP) - slot 7
The MAP is the center of the Dantel system. The MAP:
♦
Polls (interrogates) remote alarm reporting equipment
♦
Operates control points
♦
Reports alarm status to the Alarm Monitoring Center (FMAC)
The MAP uses three ports to receive and transmit information:
♦
The Data Port connects the MAP to the Control Point Module
(CPM) and Multi Alarm Transmitters (MATs) .
♦
The Printer Port, (also called the Craft, Configuration, or Inter-
face Port), is used for local monitoring and configuring of the
MAP. A serial printer can be connected here to obtain a
hardcopy printout of the alarm information.
♦
The Master Port is used to report the alarm information to the
alarm center through the E-System Adapter.
The Master Port provides mounting for the RS-232 subassem-
bly.
E-System Adapter (ESA) - slot 8
The ESA provides an interface between the MAP(s) and the TNC.
It:
♦
Takes the DCP protocol from the MAP and converts it to E2A
♦
Provides mounting for a 202 Tone Modem.
It then sends that information to the Alarm Center.
Tellabs 4003C Line Amplifier - slot 9
The 4003C Line Amplifier with Loopback provides:
♦
Switch-selectable level control.
♦
Equalization.
♦
Impedance matching in transmit and receive channels.
♦
Tone-activated or dc-activated equal-level loopback of the facil-
ity.
Dual VF 64-Kilobit Channel (64KB) - slot 10
The 64KB interfaces analog voice or data equipment to a
64-kilobit digital service channel equipment. The module has two
channels which operate independently or interconnected in bridge
configuration.
