Unbundled DS1 PRI ISDN Clause Samples

The Unbundled DS1 PRI ISDN clause defines the terms under which a telecommunications provider offers access to DS1 Primary Rate Interface (PRI) ISDN services on an unbundled basis. This means that the customer can purchase the DS1 PRI ISDN service separately from other bundled services, allowing for greater flexibility in configuring their telecommunications infrastructure. For example, a business may acquire only the ISDN PRI lines it needs without being required to buy additional services or features. The core function of this clause is to ensure that customers have the option to obtain essential digital communication lines independently, promoting competition and customer choice in the telecom market.
