Provisioning
Two provisioning methods are provided:
• Hardware
• Software (DSL service only)
Hardware Method
The HD-10 has two DIP switches for configuration
settings, refer to Figure 1. DIP switch SW3 is a
seven-position switch. Because of its location on the
printed circuit board it can only be provisioned while
the HD-10 is withdrawn from the shelf.
DIP switch SW4 is a six-position switch. It can be
provisioned from the faceplate opening while the
HD-10 is fully inserted into the backplane.
On the standalone housing, both DIP switches are
accessed by opening the housing cover.
Table 2
describes option selections for both SW3 and SW4.
CAUTION
Changing any SW3 or SW4 setting will affect
service.
A two-position jumper strap (JP1) selects the
termination for the composite clock input. Placing the
jumper in positions 2 and 3 will terminate the clock
input into 140 Ohms. Positions 1 and 2 removes clock
termination. Refer to Figure 1.
Software Method
Option settings can be seen using a VT-100 terminal
connected to the faceplate DB-9 connector. With the
exception of DSL service, option settings are
read-only on the terminal screen and can only be
changed by DIP switches SW3 and SW4.
The settings on all ten DSL modules are factory set
for 2B+D service. These settings are stored in non-
volitile RAM and can be changed using the VT-100
terminal. The settings remain in effect if power is lost
or cycled, or if the unit is removed from the channel
bank.
3. OPERATION
Integrated Operation
The HD-10 can operate with other channel bank
systems. It can be configured to operate in two modes:
8 DSL and 10 DSL. The 8 DSL mode is compatible
with any D4 channel bank that is compliant with
TR-NWT-000397 and configured for D4 terminal
with D4 counting.
The 10 DSL mode is compatible with any channel bank
that supports the ADTRAN 4:1 TDM format such as the
ADTRAN BR1/10 Channel Bank. The HD-10 does not
support D1D counting, SLC Mode 1, or SLC Mode 3.
LED Indication
The HD-10 faceplate has 13 LEDs to indicate the
operational status of the unit. Refer to
Table 3
for LED
descriptions.
Momentary Pushbuttons
The HD-10 has two pushbuttons on the faceplate:
ACO (alarm cutout) and TEST.
ACO
When an alarm condition occurs it is noted by the alarm
LED being illuminated. Depressing the ACO pushbutton
will turn off the audio and visual alarm indication and
reset the alarm relay to normal. The alarm LED will
continue to flash until the alarm condition terminates.
TEST
Depressing the TEST pushbutton initiates a bilateral
loopback test. The LBK LED will turn On solid yellow
while the test is active. Depressing the pushbutton a
second time terminates the test and the LED will go Off.
DB-9 Interface
The DB-9 connector on the faceplate provides a VT100
terminal access for provisioning, conducting tests on
individual DSLs, and performance monitoring of system
functions.
The HD-10 unit auto-detects the baud rate of the VT100
terminal. The VT100 terminal should be set to either 9.6,
19.2, or 38.4 kbaud with 8 data bits, no parity, 1 stop bit,
and no flow control. The preprovisioning process
assumes the HD-10 is inserted in a powered-up
backplane. Take these steps to access the Main Menu
screen:
1. Insert the DB-9 connector.
2. Press “enter” (continue to press "enter" until the
desired HD-10 menu appears).
If the HD-10 has remained online since the last time a
menu was accessed, then the last accessed screen will
appear first.
If the HD-10 has cycled power since the last time a
screen was accessed, then the Main Menu will appear.
