returned in this option to configure itself for proper operation. This includes binding a new

IP address, netmask and gateway (for local IP stack) as well as configuring Server 1 (minimum)

and, optionally, Server 2. By default, Server 1 is always assumed to be the primary server after a

DHCP session.

The i2004 will not accept any Offers/Acks if they do not contain:

• a Router option (i2004 needs a default router to function) AND

• a Subnet Mask option AND

• an S1 Server Address and Port

• The i20XX sets require the scope value 128 to be configured on the DHCP server as follows:

Format:

Nortel-i2004-A,iii.jjj.kkk.lll:ppppp,aaa,rrr;iii.jjj.kkk.lll:p

ppp,aaa,rrr.

where,

Nortel-i2004-A uniquely identifies this as the Nortel option

Additionally, the -A signifies this version of this specification. Future enhancements could use

-B, for example.

ASCII , is used to separate fields

ASCII ; is used to separate Primary from Secondary Business Communications Manager

information

ASCII . is used to signal end of structure

iii.jjj.kkk.lll:ppppp identifies IP:port for server (ASCII encoded decimal)

aaa identifies Action for server (ASCII encoded decimal, range 0..255)

rrr identifies retry count for Business Communications manager (ASCII encoded decimal,

range 0..255). This string may be NULL terminated, although the NULL is not required for

parsing.

Notes:

• aaa and rrr are ASCII encoded decimal numbers with a range of 0..255. They identify the

Action Code and Retry Count, respectively, for the associated Business Communications

Manager. Internal to i2004, they will be stored as 1 octet (0x00..0xFF). Note that these fields

must be no more than three digits long.

• the Business Communications Manager is always considered the Primary server; the second

server always considered Secondary.

• if only one Business Communications Manager is required, terminate primary TPS sequence

immediately with . instead of ;

e.g. Nortel-i2004-A,iii.jjj.kkk.lll:ppppp,aaa,rrr.

• valid options are one Business Communications Manager or two Business Communications

Managers (0, 3... not allowed).
