Documentation: ChannelCodeType.cs

1. Purpose

This module defines the enumeration and constants for channel code types within the DTS system. It establishes a standardized distinction between ISO 13499-compliant channel codes and user-defined channel codes, providing both type identification (via the ChannelCodeType enum) and validation constraints (via length constants) for each code type.

2. Public Interface

Class: `ChannelEnumsAndConstants`

Namespace: DTS.Common.Enums.Channels

Constants

Name	Type	Value	Description
`IsoCodeTypeString`	`string`	`"ISO 13499"`	String identifier for ISO-type channel codes
`UserCodeTypeString`	`string`	`"User"`	String identifier for user-defined channel codes
`ISO_CODE_LENGTH`	`int`	`16`	Fixed length for ISO channel codes
`USER_CODE_LENGTH`	`int`	`50`	Maximum length for user-defined channel codes

Enum: `ChannelCodeType`

Value	Description
`ISO`	Represents ISO 13499-compliant channel codes
`User`	Represents user-defined channel codes

3. Invariants

ISO channel codes must have a fixed length of exactly 16 characters (ISO_CODE_LENGTH).
User-defined channel codes must not exceed 50 characters (USER_CODE_LENGTH).
A channel code type must be either ISO or User—no other values are defined in the enumeration.
The string representation of ISO type is always "ISO 13499"; the string representation of User type is always "User".

4. Dependencies

This module depends on:

None (no imports or external references in source)

What depends on this module:

Cannot be determined from source alone. The namespace DTS.Common.Enums.Channels suggests this is part of a core utilities library likely consumed by channel-related components throughout the system.

5. Gotchas

Inconsistent naming convention: Constants use mixed naming styles—IsoCodeTypeString uses PascalCase with "Iso" capitalized, while ISO_CODE_LENGTH uses SCREAMING_SNAKE_CASE. This may
