Self-test features
The Voice Services card runs various diagnostics to detect hardware
faults and ensure correct operation. The tests include
• 8051 power-up self-tests
• BIOS diagnostics
• base code self-tests
Progress information on self-tests is available through the serial port on
the Voice Services card.
Factory-test features
Factory-test features include the HEX Display, Status LED, and Reset
Switch.
HEX display
The Voice Services card includes a HEX LED display to provide status
information during maintenance operations. During power-up and
diagnostic tests, this display provides a visual indication of progress,
and information if a failure is detected. The HEX LED display codes are
indicated in Table 2, “HEX display codes,” on page 14.
During normal operation, the display cycles through the number of
enabled Voice Services (M2616) ports, the number of booted DSP ports,
the number of channels authorized by the keycode, and the total channel
capacity of the card. For example, the HEX display appears.

You can also use the RS-232 port to monitor the progress of self-tests.
Messages indicating the completion of each self-test phase, as well as
any detected faults, print to this port.
Status LED
A single red LED on the faceplate indicates the enabled / disabled status
of the Voice Services card, as well as provides an indication of the status
of the power-on self-test.
The LED is OFF if
• the channel capacity of the Voice Services card is non-zero
and
• the card is in the normal mode of operation
The LED is ON if
• the channel capacity of the Voice Services card is zero
or
• the card is disabled from LD 32
C:XX Current capacity of card (smallest of A,D,

MAIN The card is in maintenance mode (all

Reset switch
A reset switch on the faceplate allows an operator to manually reset the
card without having to power down. This switch is normally used to
clear a fault condition during setup or non-traffic periods, and to check
firmware and loadware versions.

Risk of equipment damage
Before using the Reset switch, ensure that the Voice
Services card has been disabled in LD 32 using the
DISC command. Otherwise, some of the ports may
cause an OVD error on the Meridian 1 CPU and
become disabled when the card resets. Once the card
is active again (the HEX display has passed T:21
state), reenable the card in LD 32 using the ENLC
command.

Debug terminal access
The Voice Services card provides two RS-232 ports—one accessible via
the NTMF94AA backplane cable, and the other using the maintenance
port on the card faceplate. Only the backplane cable labeled COM1
provides access to the Voice Services card for both OA&M and
debugging purposes. The pinouts for the RS-232 ports are listed in
Table 4, “RS-232 backplane signals,” and in Table 5, “Faceplate mini-
DIN connector,” on page 17. Messages indicating the completion of
each self-test phase, as well as any detected faults, are printed.

Risk of equipment damage
Two serial connectors are available—the mini-DIN
connector on the faceplate, and the backplane cable
marked COM1. However, you can only use one
connector at one time, as both are connected to the
same serial port.
When configuring the serial communications
program, you must use the settings given in Table 3.

Debug features
While the Voice Services card is booting, the 8051 auxiliary processor
has control of the serial port, and uses it to provide debug information,
progress of self-tests, and so on. Once the 8051 releases the main
processor (i486) from reset, the main processor by default grants
VxWorks shell access through this port. The Voice Services card also
supports remote access to the shell via telnet.
Once the card is operational, the RS-232 port can be used to monitor
cardLAN and Time Compression Multiplexing (TCM) signaling
between the card and the Meridian 1 system.
Startup messages
When the card boots, a variety of diagnostic messages print to the serial
port, including hardware test results. These messages also include
firmware version information:

The VxWorks shell
The VxWorks shell is used for performing basic administrative and
management tasks, the most important of which is loadware upgrade.
You can access the VxWorks shell through a serial connection from a
PC or a telnet connection.
The shell is protected from unauthorized access by a username and
password. This password is common across FTP, telnet, and the serial
port. If the shell is idle for a period of time, the shell is logged off, and
the password and username must be reentered to gain access. This time-
out defaults to 10 minutes, but it can be set to any value between 30 and
4095 seconds (1 hour 8 minutes 15 seconds) using the shell function
shellTimeoutSet n, where nis the desired time-out in seconds. The
current value of the shell time-out in seconds is returned by the shell
function shellTimeoutGet.
-> shellTimeoutSet 600
-> shellTimeoutGet
value = 600 = 0x258
The shell (and FTP) password can be changed using the shell function
shellPasswordSet. When you use this command, it prompts you for the
current username, current password, new username, new password, and
a final confirmation of the new password.
-> shellPasswordSet
Enter current username: username1
Enter current password: password1
Enter new username: username2
Enter new password: password2
Enter new password again to confirm: password2
The shell time-out, username, and password are stored in NVRAM, so
changes are maintained across a reboot.
Once the shell username and password have been successfully
entered, the user has complete access to all the VxWorks commands.
Incorrect usage of some shell commands causes the VP to reboot, and
may change operational behavior.

To exit from the shell and return to the logon: prompt at any time, type
the command logout.
Application loadware upgrade
The Voice Services card stores up to two versions of loadware in Flash.
This mechanism ensures that if there is a power outage or other failure
during upgrade, the card still has a valid load in Flash. A small boot
code segment is located in the BIOS Flash area, which chooses the
“newest” load from one of two Flash banks to uncompress into DRAM.
Once the uncompress has completed, execution switches to the code
entry point in DRAM.
During upgrade, the Flash bank with the oldest load is erased and the
new load is stored in this area. Once the upgrade has completed
successfully, the new load is marked as “newer.” If the upgrade fails for
some reason (for example, checksum corruption), the older load
remains the boot image. A failed upgrade will not checksum correctly
and will, therefore, not be selected by the load chooser algorithm in the
boot ROM. You must reboot or reset the card for the new loadware to
execute.
Before an upgrade can be performed, the Voice Services card must first
be disabled from LD 32 using the DISC command. The Voice Services
card service on the Symposium Express Server must also be stopped.
The card is reenabled, and the service is restarted after the Voice
Services card upgrade is complete.
There are two options for upgrading the loadware. The first option is to
use an FTP Client to connect to the card, copy the loadware onto the
PCMCIA /A: or /B: disk of the card, and then do the upgrade from there
using the command “upgradePCMCIA.” This option takes the loadware
file from the PCMCIA disk and programs it into Flash. The second
option is to place the loadware file on an FTP server, and use the
“upgrade” command to retrieve the file from the FTP server and
program it into Flash. Both options are described below.
To upgrade the loadware from the PCMCIA disk
For information on upgrading the loadware, see the Symposium Express
Voice Services Card Installation Guide.
