Password Authentication Protocol (PAP) - A form of PPP authentication that requires an
exchange of user names and clear-text passwords between two devices. PAP passwords are
sent unencrypted.
Challenge Handshake Authentication Protocol (CHAP) - A form of PPP authentication
that requires an exchange of user names and secrets (encrypted passwords) between two
devices. This security feature is supported on lines using PPP encapsulation. CHAP
passwords are called secrets because they are sent encrypted.
3.2. Helpful information
This section provides information located in this user’s manual that is useful in configuring an
OmniConnect/ISDN remote access / access device.
3.2.1. Ordering an ISDN BRI line
If you have not yet ordered an ISDN BRI line, refer to the worksheet and instructions
provided at the end of this chapter, in the section entitled
ISDN Provisioning Worksheet and
Information.
3.2.2. ISDN ordering codes (IOCs) user guide
ISDN is a complex service with many network options. ISDN service is usually ordered using
ISDN ordering codes (IOCs), which simplify the connection and installation of ISDN. If your
local telephone company supports IOCs, see the sub-section entitled
ISDN Provisioning with
IOCs . If your local telephone company does not support IOCs, see the sub-section entitled
ISDN Provisioning without IOCs . To help in this process, OmniConnect products support the
most common central office switches in a variety of configurations. IOC Codes EZ-ISDN 1
(Capability U) and Capability S1 are recommended for use in North America with the
OmniConnect/ISDN access device products.
3.2.3. Cabling
The OmniConnect/ISDN access devices use a DB-9 female connector. See the section entitled
Cabling at the end of this chapter for a description on the cable connections
3.2.4. Stacking
You must remove the interlock cap (endstop) at each corner of the unit from every
OmniConnect
except the one, which will be on top. From the side of the unit, insert the tip of
a small straight-slot screwdriver into the opening of the interlock cap. Press down on the
screwdriver to pry the cap off.
Install the square rubber bumpers on the base unit.
Note:
The LanEdge products will not interlock (stack) properly if the square rubber
bumpers are installed on the interlocking (upper) unit; install these bumpers only on
the base unit.
To interlock the units into a stack, place the base unit on the desktop, then place the next unit
over the base (or stack) and press down on each corner to snap the units together. Repeat until
all units are in the assemblage.
