The
FAQ
About the 2800
Q: What is the range of the Power Supply?
A: The power supply auto adjusts to any voltage between 90-260 VAC 50/60/400 Hz.
Q: Does the 2800 come ready for installation into a 19” rack?
A: Yes, the 2800 comes with 19” rack mount brackets as standard equipment.
Q:What are the HTTP/SNMP password protection options?
A: There are two (2) passwords. The first is a monitor password which allows one to view all
configuration options and statistical data---all passwords are hidden. The second is a superuser
password which allows full configuration and password control. These passwords are the same for
the SNMP RO and RW community strings.
Q: Are all the functions of the 2800 available through the web interface?
A: Yes. All of the configuration options and statistics are available through the web interface.
Q: Is the HTTP server a separate server which communicates with the 2800?
A: No. The web server is built into the 2800 and requires no external server or system to operate.
Q: I use RADIUS, why do I need to use the static users database?
A: It is good practice to put a system administrator login into the static user database. Thus, if the
RADIUS server dies, the sysadmin can still login to the network and restart the RADIUS server.
Q: Do I have to initially use the front control panel port before using the web interface?
A: No. You can manually place a route into a WIN95 (or unix box) to gain access to the 2800. This is
done using the command “MSDOS> route add 192.168.200.1 >your-ethernet-ip-address>”. The
PC and the 2800 have to be on the same ethernet “wire”. At this point you can place the “real” IP
address for your 2800 as well as other configuration options.
Q: Why do I need a default route?
A: Often you don’t need to explicitly specify this route but good networking practice dictates that you
shouldn’t leave things to chance. Often other routers in your network will proxy-arp addresses
which your 2800 doesn’t know how to get to. In essence this is the “default” route. If you are
running RIP, the 2800 will receive this from other systems in your network.
Q: What are the 2800 hardware differences between T1/E1/PRI
A: There are no hardware differences between T1/E1/PRI connections.
Q: How is time configured in the 2800?
A: Time is a relative number based on the number of ticks since the box was rebooted. There is no
provision for entering the time of day or a date.
Q: How do I read the times that displayed? (For example: Call Duration 7:25:32.23)
A: This is read as 7 hours, 25 minutes, 32 seconds, 23 hundredths of a second.
Q: How do I set the 2800 for SS7 Signaling?
A: The 2800 currently does not support SS7. SS7 signaling is best used on the core and distribution
of the telephone network and less so on the access portion.
Q: Can I define IP filters?
A: Yes, the 2800 allows up to 20 filters to be defined and applied on a per user basis. You can also
use RADIUS to apply filters to dial-in users.
