Sync Data Port Configuration Options

Table C-3. Sync Data Port Configuration Options (1 of 5)

Port Type:		E530 (Factory 1) V.35 (Factory 2)
E530	V.35	RS449	X.21

Allows selection of the data port interface type.

E530 – Configures the port as an EIA-530-A compatible interface. EIA-530-A DTEs can be directly connected to a port connector on the back of the DSU/CSU.

V.35 – Configures the port as a V.35 compatible interface. V.35 DTEs can be connected to a port connector using an EIA-530A-to-V.35 adapter cable.

RS449 – Configures the port as an RS-449 compatible interface. RS-449 DTEs can be connected to a port connector using an EIA-530-A-to-RS-449 adapter cable.

X.21 – Configures the port as an X.21 compatible interface. X.21 DTEs can be connected to a port connector using an EIA-530-A-to-X.21 adapter cable.

NOTE: If this configuration option is set to X.21, set the Send All Ones configuration option to RTS or Disable.

Port Base Rate: Nx64

Nx64 Nx56

Allows selection of the base rate for the data port. The data rate for the port is a multiple (from 1 to 24) of the base rate specified with this configuration option.

Nx64 – Sets the base rate for this port to 64 kbps. The data rate is Nx64 kbps, where N is a number from 1 to 24.

Nx56 – Sets the base rate for this port to 56 kbps. The data rate is Nx56 kbps, where N is a number from 1 to 24.

Transmit Clock Source: Internal

Internal External

Specifies whether the transmitted data for the port is clocked using an internal clock provided by the DSU/CSU (synchronized to the clock source specified by the clock source configuration option) or an external clock provided by the DTE connected to the port. If an external clock is used, it must be synchronized to the same clock source as the DSU/CSU.

Internal – Indicates the clock is provided internally by the DSU/CSU on the TXC interchange circuit DB (CCITT 114).

External – Indicates the clock is provided externally by the DTE on the XTXC interchange circuit DA (CCITT 113). Use this selection if the clock source is set to this data port.
