ITU-T G.952 1988 Edition, November 1, 1988
DIGITAL LINE SYSTEMS BASED ON THE 2048 kbit/s HIERARCHY ON SYMMETRIC PAIR CABLES
Published By:International Telecommunications Union -Telecommunication Standardization Sector (ITU-T)
This Recommendation covers digital line systems for the transmission of signals based on the 2048 kbit/s hierarchy on symmetric pair cables and includes systems operating at the following bit rates:
2 048 kbit/s
8 448 kbit/s
34 368 kbit/s
The requirement for overall performance and interfaces of the corresponding digital line sections are given in Recommendation G.921.
