11.7 Normal and Tandem Cables
Individual E&M/TO voice cards require the purchase of the Normal mode or Tandem mode cables
listed below in Table 11-4. The type of cable used with the signaling line connector determines
whether all twelve channels of that card operate only in that mode. Physically, the Normal and Tan-
dem cables have one 96-pin DIN connector that plugs into the E&M card. The 96-pin DIN connector
has two 50 conductor, 24 AWG cables leading to two 50-pin Telco connectors. The Telco connectors
use standard RJ-2HX pinouts for 4-wire E&M, providing six channels per connector (twelve chan-
nels per card). Figure 11-8 and Figure 11-9 show the 4-wire E&M/TO cables.

11.8 Configuring Signaling Types and Trunk Processing
The 4-wire E&M/TO card is also equipped with a 4-position DIP switch for selecting between regu-
lar or clear channel E&M signaling types and setting busy or idle during trunk processing. This
switch is located at the front of the circuit board next to the 64-pin DIN connector.
