RINGCENTRAL

RingCentral System Network (Infrastructure) Requirements
An IP call transcends the entire network infrastructure between two endpoints; these performance requirements apply to that complete path, endpoint to endpoint. In a Shoreline system the endpoints are typically two ShoreGear switches or an IP phone and a ShoreGear switch.

Bandwidth
Bandwidth requirements are dictated by the concurrent number of calls on a given network segment.

Latency
Latency is the amount of time it takes for one person’s voice to be sampled, packetized, sent over the IP network, de-packetized, and replayed to another person. This one-way delay, from “mouth to ear,” must not exceed 100 msecs for toll quality voice.

Jitter for Voice Switches
Jitter is the variation of latency across the network and the variation in packet processing inside the switches.

Packet Loss
Lost packets can occur on the IP network for any number of reasons. Packet loss above 1% begins to adversely affect voice quality. This table summarizes the network requirements for bandwidth, latency, jitter, and packet loss.

Parameter Requirement
Bandwidth With ADPCM and no RTP Header Compression: 52 Kbps per call
With G.729a and no RTP Header Compression: 26 Kbps per call
With G.711 and no RTP Header Compression: 82 Kbps per call (Recommended)
Latency and jitter for toll
Quality
< 100 msecs total roundtrip from customer location to RingCentral datacenters in San Jose and/or Virginia
Latency and jitter for acceptable
Quality
< 150 msecs total roundtrip from customer location to RingCentral datacenters in San Jose and/or Virginia
Packet loss < 1% for voice calls, and no packet loss for fax and modem calls

PURECLOUD

System Network (Infrastructure) Requirements
An IP call transcends the entire network infrastructure between two endpoints; these performance requirements apply to that complete path, endpoint to endpoint.

Bandwidth
Bandwidth requirements are dictated by the concurrent number of calls on a given network segment.

Latency
Latency is the amount of time it takes for one person’s voice to be sampled, packetized, sent over the IP network, de-packetized, and replayed to another person. This one-way delay, from “mouth to ear,” must not exceed 100 msecs for toll quality voice.

Jitter
Jitter is the variation of latency across the network and the variation in packet processing inside the data switches.

Packet Loss
Lost packets can occur on the IP network for any number of reasons. Packet loss above 1% begins to adversely affect voice quality. This table summarizes the network requirements for bandwidth, latency, jitter, and packet loss.

Parameter Requirement
Bandwidth With OPUS – Auto- Adjusting CODEC used for voice and video that can fluctuate between 6 Kbps and 510 Kbps depending type of communication, available bandwidth, and call quality,
With G.711 and no RTP Header Compression: 82 Kbps per call
Latency and jitter for toll
Quality
< 100 msecs total
Latency and jitter for acceptable
Quality

Packet loss < 1% for voice calls

SHORETEL

Environment Requirements
Ventilation
Adequate ventilation must be provided to allow air circulation through the ShoreGear equipment. Leave at least two inches of open space near all vent holes

Gas and Airborne Particles
To avoid corrosion or oxidation of electrical contacts, the environment should be free from airborne particles and corrosive gas.

Lighting Protection and Grounding
The system must be properly grounded to protect from lightning damage and/or power line cross. The following condition must be met to ensure proper grounding:

A permanent earthing protector is to be installed between the system and the wiring system ground. Connect a ground wire to the screw on the back of the unit that is to the right of the product label. Connect the other end of this ground wire to the wiring system ground. Use a #16 AWG wire or larger for connectivity to the permanent earthing protector. Power supply cord: Use the provided 3-conductor power cord to connect power to the ShoreGear equipment. The power supply cord must be plugged into a grounded circuit.
A UPS is always recommended.

Specifications
Input Voltage 100-240 VAC, 50-60Hz
Power Consumption 2 A max.
Humidity 0 to 90% relative humidity (noncondensing)
Operating Temperature 0 to 50 degrees Celsius

ShoreTel System Network (Infrastructure) Requirements
An IP call transcends the entire network infrastructure between two endpoints; these performance requirements apply to that complete path, endpoint to endpoint. In a Shoreline system the endpoints are typically two ShoreGear switches, ShoreGear switch to Desktop with ShoreTel Software, or an IP phone and a ShoreGear switch.

Bandwidth With ADPCM and no RTP Header Compression: 52 Kbps per call
With G.729a and no RTP Header Compression: 26 Kbps per call
With G.711 and no RTP Header Compression: 82 Kbps per call
NOTE: If your network uses VPN, bandwidth use is affected.
Latency and jitter for toll Quality < 100 msecs total
100 msecs less 42 msecs allocated for the Shoreline system yields a 58 msec budget for the network.
When G.729a encoding is used, 100 msecs less 62 msecs allocations for the Shoreline system yields a 38 msec budget for the network.
Latency and jitter for acceptable Quality < 150 msecs total
150 msecs less 42 msecs allocated for the Shoreline4 system yields a 108 msec budget for the network.
When G.729a encoding is used, 150 msecs less 62 msecs allocated for the Shoreline4 system yields an 88 msec budget for the network.
Packet loss < 1% for voice calls, and no packet loss for fax and modem calls
