Loop-Start/Ground Start Trunks
Guidelines
• Loop-start and or ground-start trunks are connected to a LGTRK/8 card (VB-
44511) installed in a flexible slot of the cabinet. A maximum of 8 trunks can be 
connected to each LGTRK/8 card.
• Both jumpers settings and system programming determines if the circuit is used 
as a loop-start trunk or a ground start trunk. After the card in installed, the circuit 
must also be properly programmed. See Programming Section 400 - Analog 
Trunk Programming - Trunk Signal Type.
• A -48V Power Supply must be installed in the same cabinet as the LGTRK/8 card 
for ground start trunks to operate.
• One or more Trunk MDF Cards (VB-44512) must be installed to support 
connection of trunks from the Main Distribution Frame (MDF) to the LGTRK/8 
card. Each Trunk MDF supports up to three LTRK/8, LGTRK/8 or DIDTR/8 
cards (up to 24 trunks). See “Trunk MDF Interface Card” on page 5-4 for 
information on installing the Trunk MDF Interface Card.
• Each trunk card requires a four (4) RJ-11 modular cable assembly (supplied). 
• Cabling must also be completed from the MDF interface card to the MDF (cables 
not supplied).
• The maintenance switch (SW1) on the LGTRK/8 card can be set so that the card 
can be removed and installed while the system is operating. See page 5-1 for 
details on the maintenance switch.
• Table 5-5 shows the maximum numbers of cards and trunks per system type.

Installation
Note: Prior to installing the Loop Start/Ground Start Trunk Card, make certain 
you can connect to a Trunk MDF Interface Card (VB44512) mounted on the side 
of the cabinet. See “Trunk MDF Interface Card” on page 5-4 for more 
information on installing a Trunk MDF Interface Card. 
Note: Make certain that there is a -48V power supply installed in every cabinet 
containing a LGTRK/8 card.
1.  Set the jumpers for each of the circuits on the LGTRK/8 card for either ground 
start or loop start operation as per the following table:
Table 5-6.  Ground Start/Loop Start jumper settings of LGTRK/8 card 
2.  Install the LGTRK/8 card in any available flexible slot.
3.  Referring to Figure 5-5 and Table 5-7 on page 5-13, connect the trunks to the 
MDF Interface Card using the supplied modular cable assembly.
Note: Labels are supplied with the MDF Interface Card to identify the Flexible 
Slot cable connection. Make certain to attach a label on both ends of the cable 
and at the MDF Interface Card connector.
Note: After the card in installed, the circuit must also be programmed to match.
