Setting
Line buildout value for channel service unit (CSU)
lines. Valid values are as follows:
0dB—This is the default.
7.5dB
15dB
22.55dB
Not currently used. Number of active channels in a
pulse code modulation (PCM) stream.
Valid values are as follows:
isdn—Use 23 channels to carry the cells.
clear-channel—Use 24 channels to carry the
cells.
Selecting yes signifies that the ATM Forum
polynomial (coset polynomial) be added to header
error control (HEC) before the HEC verification of a
received cell. In the transmit direction, this selection
enables generation of a HEC with the coset
polynomial value.
Selecting no signifies that the ATM Forum
polynomial (coset polynomial) not be added to the
HEC before HEC verification of a received cell. In the
transmit direction, selecting no enables generation of
a HEC without the coset polynomial value.
Selecting yes enables the descrambling of received
cells on the link. The payload of transmitted cells is
scrambled.
Selecting no disables the descrambling of received
cells on the link. The payload of transmitted cells is
not scrambled.
Selecting yes enables correction of cells received with
a single-bit error in the HEC.
Selecting no disables correction of cells received with
a single-bit error in the HEC.
VPI used for VP switching, a value from 1 through
31. The rest of the valid VPIs in the valid VPI-VCI
range are used for the VC switching. Changes in this
range take effect immediately. The unit drops all
connections to make a new value effective
immediately.
This parameter is valid only when the port is in UNI
mode.
