IAO LAN ports (detail)
Overview
Alcatel-Lucent 1850 TSS-5 supports administrative LAN ports on the front of the VLNC2 SYSCTL, VLNC40, VLNC42/42B, VLNC60, VLNC61, VLNC62, and VLNC64 circuit packs. The LAN port on the SYSCTL circuit pack can be connected to the intraoffice LAN, and is also referred to as the IAO LAN port. This port is recommended for convenient, local WaveStar® CIT access. The LAN ports on the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs can be connected to the intraoffice LAN if it is functioning as a TCP/IP network. When a direct terminal or PC connection is made to either LAN port, a LAN crossover cable is required (to connect the transmit wire-pair at one end to the receive wire-pair at the other end, and vice versa).
The administrative LAN ports support 10/100BASE-T Ethernet (per Telcordia ® GR-253, ANSI/IEEE 802.2 and 802.3, and ISO 8802.2 and 8802.3) over four-wire twisted pair using an RJ-45 connector.
OSI on the IAO LAN
When the OSI protocol stack is used on an IAO LAN port of the SYSCTL circuit pack, the term OSI LAN is sometimes used. The OSI LAN is effectively an extension of the DCC. All remote operations supported over the DCC are also supported over the OSI LAN. The term DCC connectivity, used throughout this document means, DCC and/or OSI LAN connectivity.
TCP/IP on the IAO LAN
The IAO LAN port on the SYSCTL circuit pack also supports the TCP/IP protocol stack. TCP/IP communications on the IAO LAN port can be enabled or disabled. By default, TCP/IP is disabled on the IAO LAN port. When the TCP/IP protocol stack is used on an IAO LAN port, the intraoffice LAN may be referred to as a TCP/IP LAN. An IAO LAN that uses TCP/IP can be connected to a VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 LAN port and used to access the CLI.
Alcatel-Lucent 1850 TSS-5 supports TL1 over TCP/IP for the IAO LAN. As a TL1 responder, Alcatel-Lucent 1850 TSS-5 TCP/IP GNE accepts incoming TL1 connections, encoded as described, to SYSCTL circuit pack TCP port 3081 with length-value encoding.
Each TL1 message is encapsulated into the TCP data stream as follows:
-
Version number (1 byte, value set to 3)
-
Reserved (1 byte, value set to 0)
-
Length (2 bytes, value set to length in bytes of TL1 message +4)
-
TL1 Message (variable length)
The length-value encoding is the preferred encoding for machine/machine interactions.
Port 3082: Raw Encoding. Each raw encoded TL1 message is encapsulated into the TCP data stream of length 1 - 4096 bytes. The TL1 message must be parsed to find the boundary between successive TL1 messages (see Telcordia ® GR-831-CORE for the syntax of TL1 messages).
Port 3083: Telnet Encoding. The Telnet encoding is a variation on the raw encoding. It encapsulates TL1 messages in a TCP stream and uses Telnet for transmitting text over TCP/IP.
OSI or TCP/IP on the same IAO LAN
It is generally recommended that the IAO LAN port be used for OSI or TCP/IP, but not both protocols simultaneously on the same IAO LAN port.
The following figure provides examples of common connections to the Alcatel-Lucent 1850 TSS-5 from the IAO LAN.

IAO LAN compatibility
Table 5-4, IAO LAN compatibility lists Alcatel-Lucent 1850 TSS-5 IAO LAN communications compatibility with other products and the applicable OSI and/or TCP/IP protocol stacks. (WaveStar® CIT and OS access applications compatibility via the IAO LAN is covered separately later.)
