3.0 TYPICAL APPLICATION
The K Module can be deployed in one of two applications:
G.703/G.704 Network Termination (nx64kpbs to 2.048Mbps), and
G.703/G.704 Network Extension (nx64 kbps to 2.048Mbps). Both appli-
cations are discussed below.
3.1 NETWORK TERMINATION APPLICATION
Network Termination mode is used to connect a local site
modem employing a K Module to a remote site modem employing
a V.35, X.21, RS-530 Ethernet
QuikConnect
Module (refer to
Figure 1, below). Transmitter clocking is derived from the
G.703/G.704 network and carried through the system to all system
devices.

2.2 GENERAL PRODUCT DESCRIPTION
The Patton Model IM1/K G.703/G.704 QuickConnect Module and
IM2RC/K Rear Card Module provide E1/Fractional E1 termination and
extension capabilities to the Patton NetLink mDSL modems
(1095/1095RC). When used with a Patton mDSL modem, a
G.703/G.704 line can be terminated or extended to a remote site up to
10km away.
There are two separate applications that can be employed
when using the K Modules; Network Termination or Network Extension.
In a Network Termination application, the G.703/G.704 line is terminat-
ed at the K Module and the clock and data is sent to the far end of the
link. At the remote site, a Patton mDSL modem with a serial/Ethernet
interface will be running the nx64 DTE rate. This application allows the
remote user without a G.703/G.704 interface to extend the serial inter-
face that is available to the G.703/G.704 access point without the need
for a separate G.703/G.704 to serial converter. In the G.703/G.704
Network Extension application, two K Modules are employed, one at
each end of the link. This application allows the user to extend the
G.703/G.704 network over 10km away.
The K Module supports switch selectable AMI or HDB3 encoding,
all nx64 kbps bit rates and
both
dual coaxial (75 ohm) and RJ-48C
(120 ohm) G.703/G.704 terminations. The K Module is made in the
USA. The K Module is CE marked and complies to applicable CTR
standards.
