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
−
24 for T1; 0
−
31 for E1
Default: 1
Number of Channels Specifies the number of channels to be assigned to the DTE.
Values: 0
−
24 for T1; 0
−
32 for E1
Default: 24 Channel Rate
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
clock that is also supplied to the DTE as Transmit Clock. The “External”
option uses the external clock from the DTE.
Values: Internal, External
Default: Internal
NOTICE:
The “External” option is valid only in Packet mode.
Tx Invert Clock Changes the clock edge used to sample data received from the DTE.
Values: Disable, Enable
Default: Disable
Flow Control Selects the type of flow control to be used if the port is asynchronous.
Values: None, Xon/Xoff, RTS/CTS
Default: None
Character Size Selects the number of bits required to make up one asynchronous character.
Values: Five, Six, Seven, Eight
Default: Eight
Parity Sets the parity bit.
Values: None, Odd, Even
Default: None
