C ONFIGURATION All of these configurable parameters depend on whether the port is connect-
ed to a Primary Rate ISDN circuit or a Channelized T1 circuit—dedicated or
switched.
P RT
Read security: 5
Identifies the port number.
P ORT N AME
Write security: 3; Read security: 5
Accepts any alphanumeric name up to 16 characters long to uniquely iden-
tify each port.
F RAME
Write security: 2; Read security: 5
Matches the frame format of the circuit to which it is connected (available
from the network supplier).
C ODE
Write security: 2; Read security: 5
Matches the line code of the circuit to which it is connected (available from
the network supplier).
T X Y ELLOW
Write security: 3; Read security: 5
Enables and disables yellow alarm transmissions.
T X PRM S
Write security: 3; Read security: 5
Enables and disables PRM data transmissions on the facility data link
(FDL). The PRM data continues to be collected even if
T X PRM S is disabled
(possible only with ESF format).
LBO
Write security: 2; Read security: 5
Depends on whether the circuit is provisioned for DS1 by the telephone
company.
LB A CCEPT
Write security: 3; Read security: 5
Sets unit to accept or reject the in-band loop up and loop down codes as
defined in ANSI T1.403. This is a line loopback.
P ULSE D ENSITY
Write security: 3; Read security: 5
When
O N , the ATLAS 550 monitors for ones (1s) density violations and
inserts a one (1) when needed to maintain ones at 12.5%.
