Product P/N: 1186005G2
DESCRIPTION
STS-1 MUX
The MX2820 STS-1 MUX is a multiplexer unit that
1186005G2
plugs into an MX2820 chassis. The MX2820 STS-1
MUX interfaces to a standard STS-1 signal from the
ACT
network to provide 28 DSX-1 or 21 E1 outputs on the
ALM
terminal side through the demapping of 28 VT1.5s or
21 VT2s. Two MX2820 MUX cards are used together to
STAT
NET
provide a redundant STS-1 multiplexer circuit. The
TEST
MX2820 STS-1 MUX provides 1:1 redundancy and
STAT
DS1
meets the requirements for NEBS Level 3.
TEST
INSTALLATION
After unpacking the unit, inspect it for damage. If
damage is found, file a claim with the carrier and then
contact ADTRAN Customer Service. Refer to the
Warranty Statement on this Job Aid.
This module occupies a MUX slot in the MX2820
chassis. To install the STS-1 MUX in the chassis,
perform the following steps:
1. Pull the ejector tab into the down position and
gently but firmly push the MUX into the selected
MUX slot. Simultaneous thumb pressure at the
top and at the bottom of the unit will ensure a
good seat of the MUX into the backplane connec-
tor.
2. Push the ejector tab up and closed against the
front panel.
Upon installation, the MUX will begin a self-test. This
is followed with the LEDs reflecting the true state of the
hardware.
