Paper describes two different types of monitoring options for xDSL CPE (Customer Premises Equipment) detection from DSLAM (Digital Subscriber Line Access Multiplexer) side. Authors firstly present general idea of solution, particularise it for a specific application and then analyse impact of it on network devices and telco management network. The analysis focuses mainly on performance and reliability of each option for a business application, which is migration of services from ADSL/2/2+ to VDSL2 technology. Presented in the paper results and experience are based on the real telco network. 1. INTRODUCTION Copper subscriber line based digital communication is a mature technology. First ISDN specification was proposed in 1984 by the CCITT (from French: Comité Consultatif International Téléphonique et Télégraphique, now ITU-T) and now over thirty years later the ADSL/2/2+ (Asymmetric Digital Subscriber Line/2/2+) and VDSL2 (Very High Speed Digital Subscriber Line 2) following developed technologies are widely used. These ADSL family and VDSL2 techniques always coexist in one telco network. In this one telco network as well always operate few telco operators: one incumbent and alternatives ones. If we connect it with the fact that G.FAST (Fast Access to Subscriber Terminals) [1, 2] - new technique specification was released last year and continues to grow, we could be sure CPE detection is one of the most important telco technical process (specially for incumbents providing Bit-Stream Access). It is discussed in  that CPE type detection is one of the key issue for services migration between not compatible ATM (Asynchronous Transfer Mode) over ADSL/2/2+ and PTM (Packet Transfer Mode) over VDSL2 techniques. This migration process must take place because service bitrate required by customers is constantly growing, so currently the most suitable solution for copper lines is VDSL2, which could provide downstream bitrates u[...]
