TIA TSB-87-2018

Description / Abstract: Introduction

This Part presents a tutorial on the usage of the Equipment IDentifier (EID) for manufacturers of M-ESs. This Part also provides a template application form to be used in acquiring a manufacturer identifier from the Institute of Electrical and Electronic Engineers (IEEE).

The IEEE Registration Authority assigned manufacturer identifier comprises the high-order 24 bits of the EID defined in IS-732. In the EID, the manufacturer identifier is followed by a 24-bit unique CDPD M-ES number assigned by the manufacturer. The EID is used to guarantee that Temporary Equipment Identifier (TEI) requests sent by any two M-ESs are different. It appears in the following messages:

• IDENTITY REQUEST Message [IS-732-403]

• IDENTITY ASSIGN Message [IS-732-403]

• IDENTITY CHECK Response Message [IS-732-403].

The EID is further optionally used in the following Mobile Network Registration Protocol (MNRP) Messages:

• END SYSTEM HELLO [IS-732-507]

• END SYSTEM BYE [IS-732-507].

The EID is further optionally used in the following Mobile Network Location Protocol (MNLP) Messages:

• REDIRECT REQUEST [IS-732-501]

• REDIRECT FLUSH [IS-732-501]

• REDIRECT EXPIRY [IS-732-501].
