Connection to the modem port is under software 
control. 
The 1200 baud modem module maintains the com- 
patibility with the Hayes command protocol and uses 
the Bell System (Western Electric) standards 103 
and 212A for modem design. The modem operates 
on-line in both Full and Half duplex modes.

500.7 SPD 1428 & SPD 2856 TERMINALS 
A. Digital Terminal Installation: 
The Digital Terminals are interfaced with the SPD 
1428 KSU motherboard and have eight (8) circuits. 
Each of the eight (8) circuits are interfaced from the 
Ji 1 connector on the KSU motherboard to the MDF. 
The Digital Terminals are interfaced with the SPD 
2856 CKB boards which each have eight (8) circuits 
per board. Each CKB board interface is extended 
from the KSU to the MDF through the front edge 
connector on the CKB board....

The Relay Sensor Interface Module connects to the 
system using one digital station port and provides 
three relay activated contacts and three sensing 
circuits. The relays provide for applications such as 
Loud Bell Control contacts, CO Line control contacts, 
RAN Start contacts, Page Relays, Power Fail con- 
tact and additional applications as software will per-
