Port Configuration Options
Port Type: E530 (Factory 1) V.35 (Factory 2)
Next E530 V.35 RS449 X.21 Prev
Data Port Type. Allows selection of the data port interface type.
E530 – Configures the port as an EIA 530A compatible interface. EIA 530A 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 RS449 compatible interface. RS449 DTEs can be connected to a port connector using
an EIA 530A-to-RS449 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 530A-to-X.21 adapter cable.
NOTE: If this configuration option is set to X.21, 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 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
N
x64 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
N
x56 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 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 device. The sequences may be
either V.54 or FT1 (ANSI) compliant sequences.
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.
