System Overview: Trunk Cards
IP Office 500 PRI-U Trunk Daughter Card This card can be added to an IP Office 500 base card. The card is a
universal card that can be configured in software for E1 PRI, T1
robbed bit, T1 PRI or E1R2. The card is available in single and dual
port variants.
· Maximum: 4 per IP Office 500v2 control unit.
·
The IP Office 500 PRI-U card supports E1, T1 and E1-R2 PRI
modes. The Essential Edition - PARTNER® Version system
supports 8 unlicensed B-channels on each IP Office 500 PRI-U port
fitted. Additional B-channels, up to the capacity of ports installed
and PRI mode selected require IP Office 500 Universal PRI
(Additional Channels) licenses added to the configuration.
These additional channels consume the licenses based on which
additional channels are configured as in-service from port 9 of slot
1 upwards. D-channels are not affected by licensing.
2.8 SIP Cards
Essential Edition - PARTNER® Version supports both SIP trunks and SIP extensions. Because there is a wide variety of
SIP devices and interpretations of standards, Avaya cannot give any guarantees of support for all SIP extension devices
and features.
SIP Trunk Providers
Essential Edition - PARTNER® Version SIP trunks have been successfully tested with the following ITSP SIP providers.
This table of providers is a statement of fact and not any form of recommendation from Avaya, nor does it exclude other
service providers. Any details of the expected operation and service should be confirmed in writing with the individual
service provider.
The SIP Gate service does not support RFC2833 for the sending of DTMF tones. SIP Gate uses the alternate SIP INFO
method which is not supported by Essential Edition - PARTNER® Version.
Essential Edition - PARTNER® Version supports SIP trunks using UDP or TCP. For UDP SIP, STUN is supported for NAT
Firewall traversal. Otherwise use of a service provider supporting Session Border Control (SBC) is required. TURN,
sometimes used for TCP SIP traversal of NAT firewalls, is not supported.
The Essential Edition - PARTNER® Version implementation of SIP conforms to the following SIP RFCs.
RFRFCC Description
2833 [7] RTP Payload for DTMF digits, telephony tones and telephony signals.
3261 [8] SIP Session Initiation Protocol.
3264 [11] An Offer/Answer Model with Session Description Protocol (SDP).
3323 [14] A Privacy Mechanism for SIP
3489 [18]
STUN - Simple Traversal of User Data gram Protocol (UDP) Through Network Address
Translators (NATs).
3824 [24]
Using E.164 Numbers with the Session Initiation Protocol (SIP).
E.164 is the ITU-T recommendation for international public telecommunication numbering plans.
2.9 External Expansion Module
This module can be used to add additional ports to a Essential Edition - PARTNER® Version system. Only one external
expansion unit is supported
·
The external expansion module is supplied with a blue 1 meter (3'3'') expansion interconnect cable. This cable
must be used when connecting to expansion ports on the rear of a control unit.
Each module uses an external power supply unit supplied with the module. A locale specific power cord for the PSU must
be ordered separately.
