PRI / E1 / T1

PRI/E1/T1 consists of a PCI/PCIe card and a Windows client application. MultiDSLA is configured to connect to the client and can then perform tests on up to 32 64kbps channels.

PRI/E1/T1 connects digitally into a TDM telephone network; it ensures that no noise is picked up in the analogue access network and that echo conditions are controlled on the testing side. Comprehensive implementation of ISDN signalling protocols, including all international ISDN variants and QSIG, ensure easy integration with all networks.
