S-register: S68
Function:
First Active Duration
Unit: 1 ms
Range: 5–9995
Default: 2000 ms
Description: Sets the duration of the first active period of the ring signal. Any value given
to this S-register is rounded down to the nearest 5 ms. For example,
S68=1234 sets S68 to 1230 ms (1.23 seconds).
S-register: S69
Function:
First Idle Duration
Unit: 1 ms
Range: 5–9995
Default: 4000 ms
Description: Sets the duration of the first idle period of the ring signal. Any value given to
this S-register is rounded down to the nearest 5 ms. For example, S69=231
sets S69 to 230 ms (0.23 seconds).
S-register: S70
Function:
Second Active Duration
Unit: 1 ms
Range: 5–9995
Default: 400 ms
Description: Sets the duration of the second active period of the ring signal. Any value
given to this S-register is rounded down to the nearest 5 ms. For example,
S70=453 sets S70 to 450 ms (0.45 seconds).
S-register: S71
Function:
Second Idle Duration
Unit: 1 ms
Range: 5–9995
Default: 2000 ms
Description: Sets the duration of the second idle period of the ring signal (usually the
longest duration of a dual-cadence ring signal). Any value given to this S-
register is rounded down to the nearest 5 ms. For example, S71=3456 sets
S71 to 3455 ms (3.455 seconds).
S-Register: S73
Function:
MultiLink Endpoint Discriminator Type
Unit: decimal ASCII code
Range: n=0—Null Class,
n=1—Locally Assigned Address,
n=2—IP Address,
n=3—IEEE 802.1 Globally Assigned MAC Address,
n=4—PPP Magic-Number Block,
n=5—Public Switched Network Directory Number
Default: 4 (PPP Magic-Number Block)
Description: This S-register allows the MultiLink PPP Endpoint Discriminator type to be
set. The Endpoint Discriminator is used to help determine if a channel is to
be bundled with any other channels (forming a MultiLink Group or Bundle) or
if it is a new bundle. Currently, the Null Class (S73=0), PPP Magic-Number
Block (S73=4), and Public Switched Network Directory Number (S73=5) are
