The TP-1610 is offered as a 1-module (up to 240 channels or 8 trunk spans) or 2-
module (for 480 channels or 16 trunk spans only) platform. The latter
configuration supports two TrunkPack modules, each having its own IP address.
Configuration instructions in this document relate to the TP-1610 as a 1-module
platform and must be repeated for the second module as well.
TP-260 Overview
The TP-260 SIP PCI VoIP media gateway board is a complete SIP-compliant ‘media
gateway on a board’, delivering cost-effective solution in a convenient PCI form-factor. This
unique stand-alone PCI media gateway operates independently and relies on the host PCI
only for its power. The TP-260 communicates to applications using SIP using an on-board
Ethernet interface. Using a special standards-based approach eliminates host PC device
drivers and operation system dependencies, seamlessly connecting existing PSTN-based
systems to support VoIP.
The TP-260 is an ideal solution for SIP trunking gateways and integrated media gateways for
IP-PBXs and all-in-one communication servers. The board is designed for enterprise
applications or for smaller to medium PC-based systems. The TP-260 provides up to 240
simultaneous ports for voice, fax or data for VoIP media gateway applications providing
excellent voice quality and optimized packet voice streaming over IP networks. Employing
SIP as a control protocol, the TP-260 enables System Integrators short time-to-market and
reliable cost-effective deployment of next-generation networks. The TP-260 utilizes the TPM-
1100 PMC module, which is based on the VolPerfect™ architecture, 3Com' underlying core
media gateway technology.
The TP-260 matches the density requirements for small to medium locations, while meeting
NSP’s demands for scalability. The TP-260 stand-alone VoIP gateway on a board, scales
from 1 to 8 E1/T1/J1 spans in a single PCI slot and provides an excellent gateway solution
for enterprise applications as well as carrier locations.
The TP-260 supports various ISDN PRI protocols such as EuroISDN, North American NI2,
Lucent™ 4/5ESS, and others. In addition, it supports different variants of CAS protocols for
E1 and T1 spans, including MFC R2, E&M immediate start, E&M delay dial / start, loop start
and ground start.
The TP-260 enables the deployment of ‘Voice over Packet’ solutions in environments where
access is enabled to PSTN subscribers by using a trunking media gateway. This provides
the ability to transmit voice and telephony signals between a packet network and a TDM
network. Routing of the calls from the PSTN to a SIP service node (for example, Call Center)
is performed by the TP-260 internal routing feature or by a SIP Proxy.
Enabling accelerated design cycles with higher density and reduced costs, the TP-260 is an
ideal building block for scalable, reliable VoIP solutions. With the TP-260 comprehensive
feature set, customers can quickly design a wide range of solutions for PSTN and VoIP
networks.
