3Introduction
The PIKA Technologies' T1/E1 Gateway is a flexible, cost effective gateway solution that allows users to switch SIP-based VoIP
calls to T1/E1 ISDN trunks.
Based on PIKA Technologies' field-proven, patent-pending HMP (Host Media Processing) technology, the PIKA T1/E1 Gateway
can switch up to 120 simultaneous SIP calls to T1/E1 trunks supporting various ISDN PRI switch types including AT&T 4ESS,
ETSI NET5, EuroISDN, National ISDN-2, Lucent 5ESS, and Nortel DMS-100.
The PIKA T1/E1 Gateway is available with 1, 2, 3 or 4 T1/E1 spans for connection to the PSTN and includes an Ethernet port for
connection to the IP network. PIKA T1/E1 Gateway offers software expandable densities; users can start with a lower-cost 1 or 2
T1/E1 span solution and upgrade later to more capacity simply by downloading a software update.
The PIKA T1/E1 Gateway includes Echo Cancellation, Call Analysis, Fax/Modem/SIT tone detection, Span Status Notification
and Least Cost Routing capabilities. It is SIP compliant (RFC 3261) and supports G.711 (ulaw and alaw) and G.729 codecs. These
features and more can be configured via the web-based Graphical User Interface (GUI) using a standard web browser.
