Features Not Supported
•
Current loop is supported by using an external 16-port RS-232 to Current-Loop
converter. The RS-232 to 20MA Current Loop Converter (3886-CL) is a 16-port
external hardware adapter that converts, on a line-by-line basis, the AWAN 3886
RS-232 interface to current loop. Only RJ45 connectors are supported. Thus, only
the AWAN-16 and AWAN-32 models can use the 16-port current loop. An 8-Line
Cable Organizer can also be ordered for helping you manage the connecting of
RS-232 cables. Other DB9 and DB25 current-loop adapter hoods might also be
necessary, depending on your environment. See Appendix B, Current-Loop
Support for more information.
Features Not Supported
Currently, the following AWAN 3883/4/5 features are not supported on the AWAN 3886
servers even with 6530 terminal protocol support:
•
The 3886 servers have no power switches. You must connect the power cable to
power on the AWAN 3886 server.
•
Internal modem modules are not available. However, external modems are
supported.
•
Automatic leasing of the main IP address from a DHCP server.
•
On AWAN 3886 servers, the modem set-up strings are not saved in the server
configuration and are not applied on every phone call, whereas, the AWAN access
servers (3883/4/5) configure external modems on server powerup and after every
phone call.
•
Remote Telnet: Only one Telnet client or ASM client can connect to a 3886 at one
time for CLI commands.
•
VT65 emulation of 6530 on VT100/ANSI terminals and emulators is not supported.
Special 3886 AWAN Features
The following are features attributable to only the AWAN 3886 models:
•
Default AWAN 3886 server configuration supports autobaud detection.
•
Asynchronous printers can be connected by Telnet and also the Line Printer
Daemon (LPD).
•
The AWAN 3886 automatically requests its IP address, subnet mask, and gateway
address from a BOOTP server such as the Access Server Loader.
•
Software is in the form of Flash RAM, which can be installed by physically inserting
a PCMCIA memory card into the device. (The term “firmware” for AWAN 3886
units is not the same as the term used for 3883/4/5 AWANs. Firmware for AWAN
3886 units refers to the ROM firmware that is stored in non-volatile RAM (NVRAM)
on the unit and is not field-changeable.) See Flash RAM on page 1-14 for more
information on the Flash RAM memory card.
