Port Configuration Options

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

Next E530 V.35 RS449 Prev

Data Port Type. Allows selection of the data port type.

E530 – Configures the port as an EIA-530A compatible DCE. EIA 530A DTEs can be directly connected to the DB25

connector for this port on the back of the DSU/CSU.

.35

– Configures the port as a V.35 compatible DCE. V.35 DTEs can be connected to the DB25 connector using an EIA

530-to-V.35 adapter cable.

RS449 – Configures the port as an RS-449 compatible DCE. RS449 DTEs can be connected to the DB25 connector

using an EIA530A-to-RS449/422 adapter cable.

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

24) 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 24.

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 24.

Net DCLB: Disab (Factory 1) Both (Factory 2)

Next Disab V.54 FT1 Both Prev

Network Initiated DCLB. Allows initiation and termination of the Data Channel Loopback (V.54 loop 2) to be controlled by

the receipt of a DCLB-actuate sequence or DCLB-release sequence (either V.54 or FT1 (ANSI) compliant sequences)

from the network or far-end DSU/CSU.

NOTE: When this configuration option is enabled (for V.54, FT1, or both), receiving a DCLB-actuate sequence on a

particular port causes the DSU/CSU to initiate a DCLB on that port, provided that a DCLB can be performed

based on the current state of the port and DSU/CSU. Receiving the DCLB release sequence terminates the

DCLB.

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

V.54 – Enables DCLB-actuate and DCLB-release sequences that comply with the V.54 standard for ‘‘Inter-DCE signaling

for point to point circuits.”

FT1 – Enables DCLB-actuate and DCLB-release sequences that comply with the ANSI T1.403, Annex B standard for

‘‘In-band signaling for fractional-T1 (FT1) channel loopbacks.”

Both – Enables DCLB-actuate and DCLB-release sequences that comply with either the ANSI or V.54 standard. The type

of actuate and release sequences do not have to match.
