be set by configuring the next four parameters (Start Channel, Number of
Channels, Bundling, and Channel Rate).
Values: Synchronous, nx 64 kbps (where n = 1–32) or nx56 kbps (where
n = 1
−
31); or asynchronous, 1200, 2400, 4800, 9600, 19200,
38400, 57600, 115200 bps
Default: 1536 kbps
Bundling Selects whether the DTE channel assignment is made as a “Contiguous”
group or as “Alternate” channels. Selecting “Alternate” ensures ones density.
Because the unit allows individual channels to be configured for a service, a
value of “Arbitrary” will be returned for this parameter if the current channel
allocation is not contiguous or Alternate. The “Arbitrary” value can only be
supplied by the unit
−
it cannot be set by the user.
Values: Contiguous, Alternate, Arbitrary
Default: Contiguous
NOTICE: Because “Alternate” Bundling assigns every other channel, only half
the channels are available.
Start Channel Selects the starting channel in the 24-channel DS1 bit stream. Starting with
the specified channel, the unit automatically assigns the channels that follow.
Values: 1 through 24
Default: 1
Number of Channels Specifies the number of channels to be assigned to the DTE.
Values: 0 through 24
Default: 24
Channel Rate The unit can operate at any data rate that is a multiple of 56 or 64 kbps. If
“
Ν
x64K” is selected, the ones density requirements of the T1 network line
must be ensured. If “
Ν
x56K” is selected, ones density for the selected DS0
channel is maintained.
Values: Nx56K, Nx64K
Default: Nx64K
NOTICE: Start Channel, Number of Channels, and Channel Rate cannot be
changed if Bundling is not also changed from “Arbitrary.”
Format Selects the port’s operating mode.
Values: Sync, Async
Default: Sync
Tx Clock Selects the clock the unit uses to sample the data transmitted from the DTE.
When set to “Internal,” the data is sampled directly with the transmit data
