CONFIGURATION LBI-39076 B 29 CONFIGURATION OVERVIEW The user configurable parameters for the ELI option reside in two locations: the Site Controller computer’s database and the GT I units’ d atabase. T h e configuration of these two databases is covered in this section.
LBI-39076B CONFIGURATION 30 Similarly , other interconnect timing parameters may need upward adjustment. In addition to the dial to ne detect duration, the following parameters m ay require changes: pulse digit delay base, pulse digit delay increment, DTMF digit delay, DTMF digit detect duration, an d line dropping duration.
CONFIGURATION LBI-39076 B 31 • Line Active - This colum n of parame ters defin es (for the site) if a line is available for interconnect calls. Default is no (N) for all lines. Enter Y for yes, or leave N for no. Note that a line number gets its number from the radio chann el num ber that shares the same GTI Unit.
LBI-39076B CONFIGURATION 32 Who Has What Priority • Interconnect - This 1-digit field defin es (for each logical unit ID) w hich of eight queuing priority levels (from 0 to 7) is to be app lied to this specific logical unit ID for interconnect calls.
CONFIGURATION LBI-39076 B 33 Who Has What Dedicated Line • Dedicated Line - This 3-digit field def ines (for each logical unit ID) the line number to be dedicated to outgoing interconnect calls. Default is line 1. Enter a line n um ber, or 0 for denial.

OPERATION LBI-39076 B 35 OPERATION GTI UNITS The location o f the indicators and reset button o n the front panel of each GTI unit (includin g the Master GTI) is shown in Figure 43.
LBI-39076B OPERATION 36 with the Master GT I w ithin a couple of minutes of being powered-up, but in the event that it doesn’t, m omentarily press the button labeled “RESET”. CDR Received Indicator The red L ED labeled “ CDR RECEIVED” shoul d be lit mom entarily each time a Call Detail Record is receiv ed by the IAM.
OPERATION LBI-39076 B 37 Backup The IAM has the capacity to hold 60,000 records in battery back ed RAM. Every effort has been m ade to ensure that this m emory w on’t be corrup ted in normal operation.
LBI-39076B OPERATION 38 • Radio-originated call - a call from a radio using an EDACS repea ter site, through a telepho ne line connected to that EDA CS repeater site, to a telephone. • Line-connected GTI - the GTI unit connected to the telephone line for the interconnect call being described.
OPERATION LBI-39076 B 39 IDENTIFYING CALLED ID 13. T he channel-term inating GTI detects the first DTMF digit, momentarily lights the “DTMF DET ECTED” red LED on the front panel, and reports the digit to the Site Controller.
LBI-39076B OPERATION 40 PCM Data Bus (completing the audio path b etween the calling telephone and the called radio(s)). 28. The Site Controller directs the line- connected GTI to look for DTMF digits. ENDING THE CALL 29. T o end the telep hone interconnect call, the caller presse s the # key on the DT MF keypad and hangs up .
OPERATION LBI-39076 B 41 2. The radio sends an interconnect call request on the Control Channel. 3. The Control Channel GETC receives th e request for an interconnect call, and sends the request to the Site Controller.
LBI-39076B OPERATION 42 If the Dial Tone Required field is set to Y in the System Configuratio n of the GTI Configurato r, then the absence of dial tone, f or wh atever line ty pe (E&M or End-to-End), will cause the Site Controller to initiate a rotary hunt to get an available telephone line.
MAINTENANCE LBI-39076 B 43 MAINTENANCE GTI REMOVAL When y ou are about to rem o ve a GTI from an EDAC S Repeater cabinet in a w orking system , you mu st take special care to avoid disrupting th e system .
LBI-39076B MAINTENANCE 44 5. (Master GT I only) Disconnect the tw o Site Controller data link plugs from the back of the Master GTI. 6. Disconnect the PCM Data Bus f rom th e back panel of the GTI.

MAINTENANCE LBI-39076 B 49 1. System Manager (Disable All): • Using System Manager scre en 10, p anel 1 :4, reconfigu re the Interconn ect field to N for each radio channel. • Using System Manager scre en 14, r econfigure the “Line Active” field to “N” for each line number.
LBI-39076B MAINTENANCE 50 If the EL I system experiences problems due to the temporary disconnections, you w ill have to d isable the ELI sy stem through the System Manager for each temporary disconnection.
MAINTENANCE LBI-39076 B 51 TROUBLESHOOTING The hardware u sed in the ELI sy stem is extremely reliable, making component failure the unlikely cause o f most problem s.
