The ShoreGear voice switches provide the physical connectivity to voice endpoints and provide a highly reliable, highly scalable platform for the ShoreWare distributed call control software. The call control software runs on top of VxWorks, a real-time
embedded operating system designed specifically for mission-critical applications. The voice switches have FLASH memory that allows permanent storage of the call control software and configuration information. Except for a highly reliable fan, the voice switches have no moving parts (for example, no hard drive). Internal sensors
automatically monitor the fan as well as the temperature, and if any failure occurs the system can automatically notify the system administrator, through e-mail if desired. The voice switches include the necessary Digistal Signal Processor (DSP) technology to enable toll-quality voice, with features such as echo cancellation, voice compression, and silence suppression.
Each ShoreGear voice switch connects to the IP network using a 10/100M Ethernet interface. If more sites or ports are required, you simply connect additional ShoreGear voice switches to your IP network. The system is inherently scalable, unlike legacy PBX systems that have hardware growth limitations with line cards, shelves, cabinets, and systems.
ShoreGear voice switches reboot in less than 60 seconds, providing fast fault recovery. ShoreGear voice switches feature a backup operator in case the site operator is unreachable due to network outages. To use this feature, configure port 9 on ShoreGear-120/24 and ShoreGear-60/12, port 5 on ShoreGear-40/8 as an operator extension and connect an analog phone to the port.
ShoreGear-120/24
The ShoreGear-120/24 supports 24 analog ports (8 universal telephone/trunk ports and 16 telephone ports), or up to 120 IP phones. The ShoreGear-120/24 interfaces to standard analog trunks using loop-start or wink-start signaling, as well as to standard analog telephones, including CLASS feature phones with Caller ID Name and Number, and Message Waiting Indicator. This switch also supports basic media encryption at the application layer.
ShoreGear 90
The SG-90 voice switch simultaneously supports 30 IP phones and 12 analog ports. The switch is designed to be slimmer than prior ShoreGear switch models and is 1U (half-rack width). The ShoreGear 90 interfaces to standard analog trunks using loop- start or wink-start signaling, as well as to standard analog telephones, including CLASS feature phones with Caller ID Name and Number, and Message Waiting Indicator. This switch also supports basic media encryption at the application layer.
ShoreGear 90BRI
The SG-90BRI voice switch simultaneously supports 30 IP phones, 4 BRI ports and 4 analog extension ports. The switch is designed to be slimmer than prior ShoreGear switch models and is 1U (half-rack width). The SG-90BRI has 4 BRI spans, each with 2 channels and independent signaling parameters. Each span can be enabled or disabled individually. The ShoreGear 90BRI interfaces to standard analog trunks using loop-start or wink-start signaling, as well as to standard analog telephones, including CLASS feature phones with Caller ID Name and Number, and Message Waiting Indicator. This switch also supports basic media encryption at the application layer.
ShoreGear-60/12
The ShoreGear-60/12 provides 12 analog ports (8 universal telephone/trunk ports, 4 telephone ports) and up to 60 IP phones. The ShoreGear-60/12 interfaces to standard analog trunks using loop-start or wink-start signaling, as well as to standard analog telephones, including CLASS feature phones with Caller ID Name and Number, and Message Waiting Indicator. This switch also supports basic media encryption at the application layer.
ShoreGear 50
The SG-50 voice switch simultaneously supports up to 20 IP phones and offers 6 analog ports. The switch is designed to be slimmer than prior ShoreGear switch models and is 1U (half-rack width). The ShoreGear 50 interfaces to standard analog trunks using loop-start or wink-start signaling, as well as to standard analog telephones, including CLASS feature phones with Caller ID Name and Number, and Message Waiting Indicator. This switch also supports basic media encryption at the application layer.
ShoreGear-40/8
The ShoreGear-40/8 provides 8 analog ports (2 universal telephone/trunk ports, 2 loop- start trunk-only ports, and 4 telephone ports), or up to 40 IP phones. The ShoreGear- 40/8 interfaces to standard analog trunks using loop-start or wink-start signaling, as well as to standard analog telephones, including CLASS feature phones with Caller ID Name and Number, and Message Waiting Indicator. This switch also supports basic media encryption at the application layer.
ShoreGear-T1
The ShoreGear-T1 provides high-density digital voice trunking to the central office using T1, PRI, or QSIG signaling. It can also be used as a gateway to legacy PBX systems. This switch also supports basic media encryption at the application layer.
The QSIG protocol handles the signaling between digital private branch exchanges (PBXs) for Integrated Services Digital Networks (ISDN), and is based on the Q.931 standard. By designating network elements as master or slave, QSIG handles the basic signaling functions of call setup, handshaking, and call teardown, and allows PBXs from different third-party vendors to communicate and interoperate. QSIG is based on ECMA standard (see ECMA-142 and ECMA-143 for more information), and supports calling party number, and calling party name. Inbound calling party name is fully supported, but outbound calling parting name is only supported for Off-System Extension calls.
ShoreGear-E1
The ShoreGear-E1 provides high-density digital voice trunking to the central office using PRI or QSIG signaling for international installations. It can also be used as a gateway to legacy PBX systems. This switch also supports basic media encryption at the application layer.

ShoreGear 220T1
The SG-220T1 voice switch simultaneously supports 100 IP phones and a single T-1 interface that can either do PRI or CAS signaling. The switch is designed to be slimmer than prior ShoreGear switch models and is 1U (half-rack width). This switch also supports basic media encryption at the application layer.
ShoreGear 220T1A
The SG-220T1A voice switch simultaneously supports 70 IP phones, four analog extension ports, two analog extension trunks and a single T-1 interface (PRI or CAS signaling). The switch is designed to be slimmer than prior ShoreGear switch models and is 1U (half-rack width). This switch also supports basic media encryption at the application layer.
