Subject: Short Message Service (SMS) Implementation using CML Products
This document aims to assist modem product designers using and understanding Short Message Service (SMS)
applications.
CML Microcircuits' (CML) integrated circuit devices (CMX85x and CMX86x) could be used to realize and achieve a Caller
Line Identification (CLI), SMS or Low Rate Messaging Service (LRMS) data transfer
within a wireline system.

Subject: CLI with the CMX860, CMX865, CMX867 and CMX868
Caller Line ID (CLI) was originally developed for the US market but has become commonplace throughout the
World because of its multitudinous applications.
There are a number of CLI protocols to which telephone equipment manufacturers must comply.
This document gives an overview of two types; BELL GR-30-CORE/SR-TSV-002476 (or ETSI 300 659-1 section 6.1.1)
used in the USA and most of the world and Caller Line Identification Presentation (CLIP) BT SIN 227
(or ETSI ETS 300 659-1 section 6.1.2c) used in the UK.

Subject: CMX867 and CMX868 V.22bis and V.22 modem design guide
The CMX868 & CMX867 V.22bis/V.22 Modem design supports rapid development and manufacture of ultralow power
CMX868-based V.22bis and CMX867-based V.22 modems. This design has been optimized for a variety of applications
including set top boxes, point-of-sale (POS) terminals and security systems.
These documents are provided to assist users who are creating their own circuit designs.

Subject: Recommendations for V.23 1200/75 b/s duplex call set-up
V.23 recommendations do not describe how a connection is established; a procedure is described below and
illustrated in Figure 1; however you should not rely on other modems following this particular flow.
Note also that 1200/1200 bps half-duplex connections are not covered by this application note.
