hwVfbReceiveGain
Module: HUAWEI-VFB-MIB
OID (symbolic): HUAWEI-VFB-MIB::hwVfbReceiveGain
OID (numeric): 1.3.6.1.4.1.2011.6.23.1.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: port receive gain select, two userline mode range(5-10), four userline mode range(1-16) 1:-11dB, 2:-10dB, 3:-9dB, 4:-8dB, 5:-7dB, 6:-6dB, 7:-5dB, 8:-4dB, 9:-3dB, 10:-2dB, 11:-1dB, 12:0dB, 13:+1dB, 14:+2dB, 15:+3dB, 16:+4dB
What is hwVfbReceiveGain?
This read-write INTEGER (1-16) selects the receive gain applied to a VFB port, where each step corresponds to a defined dB adjustment from -11dB at value 1 up to +4dB at value 16, with the usable range depending on whether the port is in two-line or four-line mode. Admins tune this to compensate for line loss on long or noisy subscriber loops so incoming voice-frequency signal levels stay within spec. For example, raising the value from the default of 5 (-7dB) to 10 (-2dB) boosts received signal strength on a long cable run.
Examples
