Circuit packs and power supplies
334 Hardware Description and Reference for Avaya Communication Manager
● Has 33 ports, including
- One dedicated telephone access port for recording and playing back announcements
using port number 1
- One Ethernet port using port number 33
- 31 playback ports using ports 2 through 32
● Uses a 10-/100-Mbps ethernet interface to allow portability of announcements and
firmware files over a LAN
● Uses announcement files that are in ".wav" format (CCITT A- and μ-law, 8 kHz, 8-bit
mono)
The VAL can serve as an FTP or SFTP server for file transfers — primarily firmware
downloads.The VAL cannot serve as an SFTP client.
With Communication Manager Release 3.1 and later, the VAL can also receive firmware
downloads from a central firmware depository on an SCP-enabled file server.

TN799DP control LAN (C-LAN) interface
The TN799DP control LAN (C-LAN) interface provides TCP/IP connectivity over Ethernet or
Point to Point Protocol (PPP) to adjuncts such as the following:
● Avaya Call Management System (CMS)
● INTUITY AUDIX
● Distributed Communication System (DCS)
● printers
● call detail recording (CDR)
● property management systems (PMS)
The C-LAN operates at 10 or 100 Mbps and full duplex or half duplex, both of which are
administrable. The C-LAN provides connectionless UDP sockets for IP solutions support. The
C-LAN also supports 500 remote sockets, with support for 4-Kbyte UDP sockets. The C-LAN
supports variable-length ping and the traceroute and netstat network testing commands.
The C-LAN circuit pack provides call control for all IP endpoints that are connected to the
S8700-series Media Server using the G600 Media Gateway or G650 Media Gateway. A
maximum number of 64 C-LAN circuit packs can be used for each configuration. The number of
required C-LAN circuit packs depends on the number of devices that are connected. The
C-LAN number also depends on which options that the endpoints use. It might be
advantageous to segregate IP voice control traffic from device control traffic as a safety
measure.
A CLAN socket is a software object that can connect a C-LAN to the IP Network. A simple
calculation determines the default value for C-LAN socket usage of H.323 tie trunks. Divide the
total number of H.323 tie trunks that use sharing by 31. Each IP endpoint requires the use of
some number of C-LAN sockets. A C-LAN circuit pack supports a maximum of 500 sockets.
The C-LAN differs from an IP Media Processor. The difference is that the C-LAN controls the
call, while the IP Media Processor provides the codecs that are used for the audio on the call.
To keep the firmware on the CLAN circuit pack up-to-date, you can download C-LAN firmware
updates from the Web. To take advantage of this downloadable firmware capability, you must
already have at least one C-LAN circuit pack in your system. You must also have access to the
public Internet. The C-LAN can serve as an FTP or SFTP server for file transfers — primarily
firmware downloads.The C-LAN cannot serve as an SFTP client.
With Communication Manager Release 3.1 and later, the C-LAN can also receive firmware
downloads from a central firmware depository on an SCP-enabled file server.

• A processor interface (PI) if BX.25 connectivity is not required
• Eight asynchronous data channels
The TN2401/TN2400 does not include modems.
The TN2401/TN2400 is required for the SI model to save translations to the 5-volt ATA flash memory
card.
The TN2401/TN2400 complex and the TN2404 processor is required for the following upgrades:
• A G1 or G3iV1 MCC1 with a TN773 Processor
• An SI system with a TN786B Processor when reusing the existing control carrier cabinet
• An SI system with a TN790 or 790B Processor. Any R5 or R6 system will have the old control
carrier backplane and will require the TN2401/TN2400. For R7 and R8 systems, it is possible to
have the old control carrier backplane or the new control carrier backplane. The backplane type
must be verified before the upgrade order is placed so that the right characteristic selection can be
made. If the type of carrier is not known, a visual inspection of the R7 or R8 system will be
required. The old backplane is being used if the system has a TN794/TN2400 in the Network
Control.
