Configuring DPNSS signaling

When you are connecting to a DASS 2 or DPNSS switch, you must set the following parameters:

•Layer3-End specifies CCITT Layer 3. It must be set to X-Side (its default value).

•Layer2-End specifies CCITT Layer 2. It must be set to B-Side (its default value).

•NL-Value must be set to 64 (its default value).

•Loop-avoidance must be set to 7 (its default value).

Contact the service provider for more details. (These settings are not required for ISDN signaling.)

In the following example, an administrator configures DPNSS signaling using a Mercury switch (a variant of DPNSS). The specified framing mode, 2DS, is a variant of G.703 required by most E1 DPNSS providers in the United Kingdom. To configure an E1 line for DPNSS signaling, proceed as in the following example:

admin> read e1 {1 2 2}

E1/{ shelf-1 slot-2 2 } read admin> set enabled = yes

admin> set signaling-mode = e1-dpnss-signaling admin> set switch = mercury-dpnss

admin> set frame-type = 2ds admin> set layer3-end = x-side admin> set layer2-end = b-side admin> set nl-value = 64
