Introduction
Demarcation Cabinet for J-Series Codec
The J-Series video codec is a primary component of Grass Valley’s DS-3
network video transportation products. It provides an economical,
signal-multiplexing capability which can combine high-quality video,
audio, and data, and format it for transmission over standard DS-3
telecommunication links. The J-Series codec interfaces with DS-3, T1,
RS-232, and RS-485.
The J-Series codec is an NTSC-compatible, composite video codec. A
proprietary implementation of the JPEG compression scheme is used to
deliver near-broadcast quality, full motion video at 30 frames per second.
The J-Series Codec Demarcation Cabinet is a metal interface box designed
to house multiple J-Series codecs. The cabinet protects the equipment
inside and prevents unauthorized access to the codec(s).

Section —Demarcation Cabinet for J-Series Codec
Physical Description
The J-Series Demarcation Cabinet (Demarcation Cabinet) is a cabinet that is
mounted on a wall. The cabinet protects the equipment inside and prevents
access to the codec(s) by unauthorized personnel. It can hold one 6 RU
codec (J10) or up to three 2 RU codecs (J3).
The codec units are installed onto standard rack-mounting holes on the
Demarcation Cabinet door‘s swing- frame assembly. A wire cable harness
from an Interface Panel connects to the backplane of the codec(s) that
mounts on the inside of the cabinet. The Interface Panel replaces any one of
the four cover plates on the sides of the cabinet. See Figure 1.
NOTE:
Hardware Specifications
The physical specifications of the J-Series Demarcation Cabinet are
presented in Table 1.
