5.4 Huawei MA5116S
The Huawei MA 5116S DSLAM family uses a pair of Amphenol connectors to connect to the
telephone switch located at the CO that provides the dial tone on each pair along with the -48Vdc
sealing current.
The POTS Splitter integrated in the Huawei MA 5116S series DSLAM will merge the -48Vdc from the
POTS pairs with the DSL signal from the DSLAM onto the DSL ports.
NOTE:
In order for the -48Vdc current to flow through the DSLAM, it is important to insert a 5-pin Gas
Tube Discharge device (Bourns or similar) in the corresponding socket for each pair requiring BRX
amplification.
