On the NT8D37EC shelf, in Figure 4, the backplane connectors L1, L2, and L3
from each card slot cable to an input/output connector. Also, on this shelf, a
Voice Services card works in any card slot from 0 to 15. See Figure 4.

The NTMF94BA cable breaks out the backplane signals into an Ethernet port
(10-Base-T) and a serial RS-232 port. This is the same RS-232 port as is
presented to the faceplate mini-DIN connector.
The Ethernet port of the NTMF94BA has a single female RJ-45 connection, so
that a standard 10-Base-T Ethernet cable can be used to connect it to the LAN/
hub. The female adapter included with the cable can be removed if the RJ-45
cable can be plugged directly into the ELAN hub. The NTMF94BA cable is
secured to the I/O panel using a screw and a cable tie (large systems only).

The RJ-45 cable must be installed on the ELAN to provide more
reliability. Although the card is installed on the ELAN, you manage the card
from the CLAN from a client PC.
On the NT8D37DC shelf, in Figure 5, the backplane connectors L1, L2, and L3
from card slot 0, 4, 8, and 12 are cabled to I/O connectors A, E, K, and R. The
remaining card slots have only backplane connectors L1 and L2 cabled to the
I/O connectors. With the NT8D37DC shelf, a Voice Services card only works in
card slots 0, 4, 8, and 12, unless you install cable NT8D81AA. See Figure 5.
