Port Configuration Options

Port Type: E530
Next     E530     V.35     RS449     Prev

Data Port Type. 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 the
DB25 connector on the back of the E1 DSU/CSU.

V.35 – Configures the port as a V.35 compatible interface. V.35 DTEs can be connected to the DB25 connector using an
EIA-530-A-to-V.35 adapter.

RS449 – Configures the port as an RS-449 compatible interface. RS-449 DTEs can be connected to the DB25 connector
using an EIA-530-A-to-RS-449 adapter.

NOTE: For X.21 applications, set this configuration option to RS449 and set the All Ones configuration option to RTS or

Disab.

Base Rate: Nx64
Next     Nx64     Nx56     Prev

Data Port Base Rate. Allows selection of the base rate for the data port. The data rate for the port is a multiple (from 1
to 31) of the base rate specified with this configuration option.

Nx64 – Sets the base rate for this port to 64 kbps. The data rate will be Nx64 kbps, where N is a number from 1 to 31.

Nx56 – Sets the base rate for this port to 56 kbps. The data rate will be Nx56 kbps, where N is a number from 1 to 31.

Net DCLB: Disab
Next     Enab     Disab     Prev

Network Initiated DCLB. Allows the initiation and termination of a Data Channel Loopback (V.54 loop 2) by the receipt of a
V.54 DCLB-actuate sequence or DCLB-release sequence from the network or far-end E1 DSU/CSU.

Enab – Allows the E1 DSU/CSU to begin a DCLB for this port when it receives a DCLB-actuate sequence (if the current
E1 DSU/CSU state allows a DCLB to be performed). Receiving a DCLB-release sequence terminates the  DCLB.

Disab – Ignores the DCLB-actuate and DCLB-release sequences for this port.

Port LB: Disab
Next     Disab     DTLB     DCLB     Both     Prev

Port (DTE) Initiated Loopbacks. Allows the initiation and termination of a local Data Terminal Loopback (DTLB) or remote
Data Channel Loopback (DCLB) by the DTE connected to this port. (DTLB is equivalent to a V.54 loop 3, and DCLB is
equivalent to a V.54 loop 2.) Control of these loopbacks is through the DTE interchange circuits as specified by the V.54
standard.

Disab – Disables control of local DTLBs and remote DCLBs by the DTE connected to this port.

DTLB – Gives control of the local DTLBs for this port to the DTE attached to this port. This loopback is controlled by the
Local Loopback interchange circuit LL (ITU-T 141).

DCLB – Gives control of the remote DCLBs for the far-end port connected to this port to the DTE attached to this port.
This loopback is controlled by the Remote Loopback interchange circuit RL (ITU-T 140). The far-end equipment must
support in-band V.54 loopbacks.

Both – Gives control of local DTLBs and remote DCLBs to the DTE connected to this port.
