282 NT5D33 and NT5D34 Lineside E1 Interface cards
the connection of the NT5D35AA or NT5D36AA LEI card carrier and
maintenance external I/O cable at the IPE and CE module I/O panel
connector for card slots that are otherwise restricted.
Alternatively,all LEI connections can be made at the main distribution frame
instead of connecting the NT5D35AA or NT5D36AA LEI card external I/O
cable at the I/O panel. This eliminates these card slot restrictions.
Cabling the LEI card
After the dip switches are configured and the LEI installed into the selected
card slots, the LEI can be cabled to the LTUequipment, the MMI terminal
or modem (optional), an external alarm (optional), and other LEIs fordaisy
chaining use of the MMI terminal (optional).
The LEI is cabled from its backplane connector through connections from
the motherboard circuit card only to the I/O panel on the rear of the IPE
module. No cable connections are made from the daughterboard circuit
card. The connections from the LEI to the I/O panel are made with the
NT8D81AA Tip and Ring cables provided with the IPE module.
Cabling from the I/O panel with the NT5D35AA or NT5D36AAlineside E1 I/O cable
In a twisted-pair E1 installation, make the connection from the I/O panel
to the E1 link and other external devices with the NT5D35AA lineside E1
I/O cable.
This cable consists of a 25-pair amphenol connector (P1) on one end which
plugs into the I/O panel. The other end has four connectors:
1. a DB15 male connector (P2), which plugs into the E1 line
2. a DB9 male connector (P3), which plugs into an external alarm system
3. a second DB9 male connector (P5), which connects to an MMI terminal
or modem
4. a DB9 female connector (P4), which connects to the next LEI’s P4
connector for MMI daisy chaining
In a coaxial E1 installation, make theconnection from the I/O panel to the E1
link and other external devicesthrough the NT5D36AA lineside E1 I/O cable.
This cable consists of a 25-pair amphenol connector (P1) on one end which
plugs into the I/O panel. The other end has 4 connectors:
1. a DB15 female connector (P2) with an adapter that breaks out Tx
(transmit) and Rx (receive) connectors,which that plug into the E1 line
2. a DB9 male connector (P3), which plugs into an external alarm system
