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/A, CMX867/A and CMX868/A
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: 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.

Subject: CMX868/A and CMX869/A/B Modems with CLARE Litelink DAA
This application note describes how the Clare CPC5621 optical DAA can be used to interface the CMX868 V.22bis and
CMX869 V.32bis modem chips to the telephone line.
The primary benefit of the Clare LightLink DAA is that it requires very little board area and has a very low
profile. This can be important in applications where there are tight space constraints.

CMX868 Programmer's Quick Reference
With modern fabrication techniques it is becoming increasing common to see more peripheral circuits added to the
basic functionality of integrated circuits.
This trend toward increasingly complex devices is good for the user in that it simplifies the overall design,
reduces external hardware and lowers cost whilst giving increased flexibility.
The trade-off is that the device becomes more difficult to understand and manage as previously separate functions
become interrelated and inter-dependent.

Subject: CMX867/A and CMX868/A 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: C-BUS Coding Example Using the CMX868/A
The purpose of this document is to provide example programs that can be used to control a C-BUS compatible device.
The CMX868A V.22 bis wireline modem IC utilizes a C-BUS interface and will be used as the platform for the programs
listed in this document.
