NT5D11 and NT5D14 Lineside T1 Interface cards Page 213 of 906Circuit Card Description and InstallationCabling the lineside T1 cardAfter configuring the dip switches and installing the lineside T1 card into theselected card slots, the lineside T1 card is ready to be cabled to the CPE orCSU equipment. Connections can also be made to the MMI terminal ormodem (optional), an external alarm (optional), and other lineside T1 cardsfor daisy-chain use of the MMI terminal (optional).The lineside T1 card is cabled from its backplane connector throughconnections from the motherboard circuit card only (no cable connections aremade from the daughterboard circuit card) to the input/output (I/O) panel onthe rear of the IPE module. The connections from the lineside T1 card to theI/O panel are made with the NT8D81AA Tip and Ring cables provided withthe IPE module.Cabling from the I/O panel with the NT5D13AA lineside T1 I/OcableUsually, the I/O panel is connected to the T1 link and other external devicesthrough the NT5D13AA lineside T1 I/O cable. See Figure 32 on page 214.This cable consists of a 25-pair amphenol connector (P1) on one end whichplugs into the I/O panel. The other end has 4 connectors:1 a DB15 male connector (P2) which plugs into the T1 line2 a DB9 male connector (P3) which plugs into an external alarm system3 a second DB9 male connector (P5) which connects to an MMI terminalor modem4 a DB9 female connector (P4) that connects to the next lineside T1 card’sP4 connector for MMI daisy chainingCabling from the I/O panel at the Main Distribution FrameAll lineside T1 connections can be made at the main distribution frame(MDF) if it is preferred to not use the NT5D13AA lineside T1 I/O cable at theI/O panel.
