3.1.3. Features 
OpenScape 4000 SoftGate offers the following features:
- Runs on standard server hardware.
- Operated with the Suse Linux Enterprise Server (SLES) operating system.
- Integrated media server.
- Administration via OpenScape 4000 Assistant/Manager.
- Integration in OpenScape 4000 networks.
- Supports all functions of IP Distributed Architecture (IPDA) (see Chapter 1,
“IPDA Feature Description”).
- Supports OpenScape 4000 IPDA survivability options: signaling survivability and connection to existing AP emergency servers.
- Supports a/µ law conversion per OpenScape 4000 SoftGate. For more information on a/µ law conversion please refer to the service manual “OpenScape 4000 V/, Section 4- IP Solutions > IP Distributed Architecture”.
- Each OpenScape 4000 SoftGate has the following sources available:
- 64 TSLs for conference
- 32 receivers for DTMF signaling (CR)
- 32 sender for DTMF signaling (CS)
- 2 continuous-tone dial tone receivers (DTR-DT)
- 2 cadenced-tone dial tone receivers (DTR-TT)
- 2 test receivers (TESTR)
- 1 test sender (TESTS)
- up to 18 different tones and 6 different announcements (for a detailed description please refer to IP Distributed Architecture > Section 2.16, “Different Announcements, Tones and DTMF DialTone Receivers per Access Point”.)
- 5 different display languages/national character sets different to the host system and/or different for each OpenScape 4000 SoftGate (for a detailed description please refer to IP Distributed Architecture > Section 2.17, “Different Languages/National Character Sets for Displaying Text for Individual Access Points”.)
- 1 music on hold
- 1 TDS port
- Maximum number of parallel calls: 250
- Supports DMC - OpenScape 4000 SoftGate is DMC endpoint (see “Payload Switching DMC”, Chapter 4, “Direct Media Connect (DMC) in Connection with OpenScape 4000 SoftGate”). Activation of DMC does not cause a channel reduction like in STMI/NCUI, as DSPs are software not hardware based. Maximum number of calls remains as configured, with or without DMC.
- Supports T.38 Fax (see T.38 Fax).
- Supports signaling and payload encryption
-
More information about “Signaling and Payload Encryption (SPE)” can be found in the respective section.
- Supports ISDN calls in the public network. PSTN connections are conducted via Mediatrix SIP gateways.
- Analogue and fax connection
- via AP 3700 in conjunction with OpenScape 4000 SoftGate 1000.
- via Mediatrix 41xx SIP gateway in conjunction with OpenScape 4000 SoftGate 50 (see Section 3.3.5, “Analog Stations (Mediatrix 41xx)”).
- S0 connection via Mediatrix 44xx SIP gateways:
- S0 subscriber: Section 3.3.1, “ISDN (S0) Subscriber (Mediatrix 44xx)”
- S0 trunking: Section 3.3.2, “S0 Trunking (Mediatrix 44xx)”
- S0 data connection: Section 3.3.3, “ISDN (S0) Data Connections (Mediatrix 44xx)”
- Mediatrix 35xx for PRI interface for T1.
- Mediatrix 36xx for PRI interface (see Section 3.3.4, “S2 Interface (Mediatrix 36xx)”) for E1.
- Mediatrix 1204 for analog trunking (see Section 3.3.6, “Analog Trunking (Mediatrix 1204)”).
- Video integration with LifeSize terminals (see Chapter 5, “Video Connections”).
- Supports native SIP and SIP-Q trunking.
- IPv6 for SIP-Q and native SIP trunking with OpenScape 4000 SoftGate (see Chapter 12, “IPv6”).
- End-to-end payload connections between native SIP trunks and SIP stations.
- Native SIP trunking enhancements:
- configurable voice codecs for HG 3500 per destination gateway or IP sub network
- native SIP trunking features: message waiting indication, call transfer and call forwarding
- SIP service provider connections are possible.
-
INFO:
The firewall and SBC (session border control) configuration is dependent on the customer network and NAT (network address translation). - HiPath Cordless IP V1 has been released for connection to the OpenScape 4000 SoftGate (see HiPath Cordless IP).
- For increased resilience, OpenScape 4000 SoftGate can be connected with two LAN cables to different switches/router (see Chapter 6, “LAN Redundancy”).
- Gatekeeper Redundancy for HFA Subscriber (see Chapter 10, “Gatekeeper Redundancy for HFA/ SIP Subscriber”).
- Survivable OpenScape 4000 SoftGate (see Chapter 11, “Survivable OpenScape 4000 SoftGate”).
- SIP Load balancing for inbound native SIP trunks. With load balancing the system is to be able to scale the performance of involved SIP servers, to avoid overloading of the server and to achieve high availability of the SIP services (see Chapter 13, “Load Balancing”).
- OpenScape Access modules can be connected directly to the OpenScape 4000 SoftGate. For information on licensing see OpenScape Access/Branch service documentation.
- With the release of OpenScape Access/Branch the vNCUI can act as (secure) DMC endpoint.
- QDC is supported.
- OpenScape Cordless E Integration (see Chapter 17, “OpenScape Cordless E Integration”).
- MFC-R2 support (see Chapter 16, “MFC-R2”).
- 16 peripheral slots for virtual boards and OpenScape Access modules
-
Each virtual board within the OpenScape 4000 SoftGate uses one slot of it. Due to the enhanced number of slots, the installation of virtual boards consumes no longer hardware slots on OpenScape Access and OpenScape 4000 SoftGate.For traces please make sure that the assignment between slot and PBC number is correct (see Section 1.8, “Hints for Diagnosis regarding the peripheral Slots”).
