ACCULINK 316x DSU/CSU
Port Configuration Options
Port Type: E530 (Factory 1)
Next E530 V.35 RS449
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.
V.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)
Next Disab V.54 FT1
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.
