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
complete. The PPP Magic-Number Block contains 5 Magic-Numbers in this
implementation and is the default type. The Public Switched Network
Directory Number option uses Data Directory Number 1 as the Endpoint
Discriminator (if it is blank, then Endpoint Discriminator is blank). The
Locally Assigned Address (S73=1), IP Address (S73=2), and IEEE 802.1
