 NT5D11 and NT5D14 Lineside T1 Interface cards

Begin the installation and configuration of the lineside T1 card by selecting 
the proper dip switch settings for the environment. The lineside T1 card 
contains two dip switches, each containing eight switch positions. They are 
located in the upper right corner of the motherboard circuit card as shown in 
Figure 28 on 

. The settings for these switches are shown in Tables 75 

through 78.

When the line-side T1 card is oriented as shown in Figure 28 on 

dip switches are ON when they are up, and OFF when they are down. The dip 
switch settings configure the card for the following parameters:

This dip switch setting selects the appropriate baud rate for the terminal or 
modem (if any) that is connected to the MMI.

As described in “Lineside T1 call operation” on 

, the lineside T1 card 

is capable of supporting loop start or ground start call processing modes. 
Make the selection for this dip switch position based on what type of line 
signaling the CPE equipment supports.

The address of the lineside T1 card to the MMI is made up of two 
components: 

•

The address of the card within the shelf 

•

The address of the shelf in which the card resides

These two addresses are combined to create a unique address for the card. The 
MMI reads the address of the card within the shelf from the card firmware; 
however the address of the shelf must be set by this dip switch.

The shelf address dip switch can be from 0 – 15. 16 is the maximum number 
of lineside T1 IPE shelves (a maximum of 64 lineside T1 cards) capable of 
daisy chaining to a single MMI terminal. For ease, it is recommended that this 
address be set the same as the address of the peripheral controller identifier in
