Network Initiated Data Channel Loopback (9128)

Possible Settings: Disable, V.54, ANSI_FT1, V.54_&_ANSI

Default Setting: Disable

Allows the initiation and termination of the Data Channel Loopback (V.54 Loop 2) to be controlled by the receipt of a DCLB-actuate and DCLB-release sequence (either V.54, or FT1 [ANSI] compliant sequences) from the network or far end unit. When this configuration is enabled (V.54, FT1, or Both), receiving a DCLB-actuate sequence on a particular port causes the unit to initiate a DCLB on that port (provided that a DCLB can be performed based on the current state of the port and unit). Receiving a DCLB-release sequence terminates the DCLB.

Display Conditions – This option only appears for Port-2 on a FrameSaver SLV 9128, when Port Use is set to Synchronous Data.

Disable – Ignores the DCLB-actuate and DCLB-release for the port.

V.54 – DCLB-actuate and DCLB-release sequences that comply with the V.54 standard for “inter-DCE signaling for point-to-point circuits” are recognized and will control the initiation and termination of a DCLB (V.54 Loop 2) for the port.

ANSI_FT1 – DCLB-actuate and DCLB-release sequences that comply with either the ANSI.403, Annex B standard for “in-band signaling for fractional T1 (FT1) channel loopbacks” are recognized and will control the initiation and termination of a DCLB for the port.

V.54_&_ANSI – DCLB-actuate and DCLB-release sequences that comply with either the ANSI or V.54 standard are recognized and will control the initiation and termination of a DCLB for the port.

EIA-530-A/X.21/V.35 Data Port Physical Interface

FrameSaver Models 9788, 9820-2M, and 9820-8M have an EIA-530-A data port that can be adapted for use as an X.21 or V.35 data port.

Table 3-16. EIA-530-A/X.21/V.35 Data Port Physical Interface Options (1 of 3)

Port Type

Possible Settings: E530, V.35, X.21

Default Setting: V.35

Specifies the port type of the data port.

E530 – The port is configured as an EIA-530-A-compatible DCE. An EIA-530-A- compatible DTE may be directly connected to the DB25 connector for the port.

V.35 – The port is configured as a V.35-compatible DCE. A V.35-compatible DTE may be connected to the port using a DB25-to-MS34 adapter.

X.21 – The port is configured as an X.21-compatible DCE. An X.21-compatible DTE may be connected to the port using a DB25-to-DB15 adapter.
