HIGH-DENSITY MODEM TESTER for RAS devices and universal port gateways. The Hammer Universal Port with Modem Tester (UPM) delivers real-world traffic patterns, including mixes of modem, voice, tones and fax traffic. The system is capable of generating up to 240 channels of modem traffic across up to 12 T-1 or E-1 spans controlled with CAS, ISDN PRI or SS7 signaling. The Hammer UPM can be configured to emulate a mix of client types, including V.90 and V. 34. Following session establishment, each channel can ping a remote IP address and generate summary metrics for each modem connection, session training and ping test.--Empirix
