Reference GuideProduct Overview The Cisco Unified Communications 540 (Figure 1) part of the Cisco Unified Communications 500 Series for SmallBusiness, is a critical part of the Cisco Smart Business Communications System. It is an affordable unifiedcommunications appliance that provides voice, data, voicemail, automated attendant, video, security, and wirelesscapabilities while integrating with existing desktop applications such as calendar, email, and customer relationshipmanagement (CRM) programs. This easy-to-manage platform supports up to 32 phones and voice mailboxes andprovides flexible deployment options based on your needs, including support for a wide array of IP phones, publicswitched telephone network (PSTN) interfaces, and Internet connectivity. This reference guide describes thespecifications and capabilities of the Cisco Unified Communications 540 (UC 540).Figure 1.Cisco Unified Communications 540 Models: FXO (Left) and BRI (Right)Product Part NumbersThe Cisco UC 540 is available in two versions, an FXO (analog) model and a Basic Rate Interface (BRI) base model.With ease of ordering as a focus area, each has its own product ID. In addition, there is one software licensingproduct, multiples of which can be installed to achieve the desired user count. Table 1 lists the part numbers for theCisco UC 540.Table 1.Product Part Numbers for the Cisco UC 540Part NumberDescriptionUC540W-FXO-K9UC 540 system with 4 FXO, 4 FXS, and 1 voice interface card (VIC) expansion slotUC540W-BRI-K9UC 540 system with 2 BRI, 4 FXS, and 1 VIC expansion slotL-UC-PRO-8U Software license upgrade, authorizing an additional 8 users (eDelivery)Interfaces and ModulesThe Cisco UC 540 has built-in interfaces that offer fixed configurations, reducing complexity. In addition, this platformoffers one (1) voice interface card (VIC) slot to support additional Cisco VIC modules. Table 2 lists the built-ininterfaces, and Table 3 lists the modular interfaces supported on the UC 540.Table 2.Built-In Interfaces Supported on the Cisco UC 540InterfaceDescriptionMusic-on-hold portSingle 3.5-mm audio portOnboard Ethernet ports Eight 10/100 Mbps LAN One 10/100 WAN uplink One 10/100 Ethernet expansion portIntegrated inline Power over Ethernet (PoE) ports8 built-in PoE portsFXS and direct inward dialing (DID) ports4 built-in FXS ports (DID is available via the additional module listed in Table 3)PSTN interfaces (FXO or BRI)4 FXO or 2 BRI ports 2009 Cisco Systems, Inc.

These licenses enable the use of Cisco Unified IP Phones and allowusers to access the IP PBX features, including voicemail. In addition, supplementary user licenses are bundled tohelp with deployments that need a few extra licenses. For additional licensing needs, the L-UC-PRO-8U may beordered. This increases the existing license count by eight. Table 5 lists the number of users supported based on thehardware/license configurations. The UC 540 also has built-in licenses for unified communications features. Table 4lists the license count bundled within the system for each feature. Guidance for licenses associated with voicemessaging on the UC 540 is included in Table 6.Table 4.Licensing and User Capacity for the Cisco UC 540License ConfigurationDescriptionUC540W-FXO-K9 or UC540W-BRI-K98 user licenses, 2 supplemental user licensesUC540W-FXO-K9 or UC540W-BRI-K9 and one L-UC-PRO-8U 16 user licenses, 2 supplemental user licensesUC540W-FXO-K9 or UC540W-BRI-K9 and two L-UC-PRO-8U 24 user licenses, 4 supplemental user licensesUC540W-FXO-K9 or UC540W-BRI-K9 and three L-UC-PRO-8U 32 user licenses, 4 supplemental user licensesTable 5.Feature Licensing for the Cisco UC 540FeatureNumber of Licenses IncludedVirtual LANs (VLANs)5Service Set Identifiers (SSIDs)3Broadcast SSIDs (BSSIDs)1VPN tunnels*10Remote teleworker sites10Users per teleworker site5Multisite deployments5* Includes IP security (IPSec), Secure Sockets Layer (SSL), or generic routing encapsulation (GRE) tunnels. 2009 Cisco Systems, Inc.

Any combination of personal mailboxes andgeneral delivery mailboxes can be used.** There are 20 simultaneous sessions available between IMAP Client and IMAP server. If all 20 sessions are used up, theremaining session requests will be rejected by the IMAP server. IMAP clients will automatically attempt to establish session with theserver once some of the server ports are freed up. This does not limit the number of IMAP clients to 20.Basic Call Center CapabilitiesThe Cisco UC 540 supports basic automatic call distribution (BACD) that can help answer outside calls withgreetings and menus and allow callers to select the appropriate departments. BACD also provides managed callqueues for calls that are waiting to be answered. Table 7 lists the BACD capabilities of the UC 540.Table 7.Cisco UC 540 BACD CapabilitiesFeatureNumberHunt groups associated with a BACD10Calls allowed in each call queue30Agents (members) for each hunt group20Statistics accumulated for all BACD groups168 hoursHunt groups used with automated attendant3In addition to BACD, the Cisco UC 540 integrates with Cisco Unified Contact Center Express (UCCX). UCCX workswith up to a maximum of 12 users (agents and supervisor combined) on the UC 540.Voice Resource UtilizationThe Cisco UC 540 includes four digital signal processors (DSPs) that enable digitized voice processing on theplatform. The DSP resources available on the platform are used for various unified communications features, namelysupport of analog and digital VICs, prescheduled or ad hoc voice conference calls, and translation of digitized voicefrom a less complex codec (such as g711) to a more complex codec (such as g729)—typically used for deploymentsthat use IP trunking (SIP or H.323) for PSTN access or multisite interconnection.Each DSP can support 16 g711 channels or 8 g729 channels. This enables a total of 64 g711 channels on the CiscoUC 540. Table 8 indicates the DSP resource utilization based on the feature. Tables 9 and 10 show a fewdeployment scenarios based on the combination of these features. 2009 Cisco Systems, Inc. All rights reserved. This document is Cisco Public Information.Page 5 of 11

The rest of the features can share a DSP. The number of sessions available willvary depending upon the codec used in a conference call.Tables 9 and 10 list maximum sessions for either ad hoc conferencing or meet-me conferencing. DSP resourcesallocated for conferencing can be shared by both features, and a mix of these can be configured. Below are a fewexamples based on Table 9. The concept of sharing conferencing resources applies to Table 10 as well.Ad hoc 24x8Meet-me 0x0Ad hoc 12x8Meet-me 12x8Ad hoc 24x4Meet-me 6x16The above examples indicate Sessions x participant.The Transcoding column lists the maximum transcoding sessions that the system can be configured for, for a givenconfiguration of DSP. For example, the first row in Table 9 indicates that a maximum of three transcoding sessionsare available if three DSPs are allocated for conferencing.If more transcoding sessions are required, DSP resources will need to be diverted from conferencing to transcoding.For example, in the second row of Table 9, one of the DSPs is dedicated to transcoding, leaving two DSPs forconferencing. Notice the increase in the number of transcoding sessions and the drop in the number of conferencingsessions.Table 9.DSP Resources: Scenario 1UC 500ModelAdditionalVoice Card(VIC)SIP TrunkPreferred CodecAd-hocConference(Sessions xParticipants)Meet-meConference(Sessions xParticipants)UC 540NoneNo SIP Trunk orG.711Up to a maximumof 24x8 or 48x4Up to a maximumof 24x8 or 12x16or 6x32 1 DSP for supporting voice ports and Transcodingsessions Remaining 3 DSPs used for ConferencingA maximum of 3Transcoding sessions forthis configurationG.729Up to a maximumof 4x8 or 8x4Up to a maximumof 4x8 or 2x16 or1x32 1 DSP for supporting voice ports and Transcodingsessions 1 DSP reserved for transcodingA maximum of 11Transcoding sessions forthis S/DIDNo SIP Trunk orG.711Up to a maximumof 24x8 or 48x4Up to a maximumof 24x8 or 12x16or 6x32 1 DSP for supporting voice ports and Transcodingsessions Remaining 3 DSPs used for ConferencingA maximum of 2Transcoding sessions forthis configurationG.729Up to a maximumof 4x8 or 8x4Up to a maximumof 4x8 or 2x16 or1x32 1 DSP for supporting voice ports and Transcodingsessions 1 DSP reserved for transcodingA maximum of 10Transcoding sessions forthis D Remaining 2 DSPs used for ConferencingNo SIP Trunk orG.711Up to a maximumof 24x8 or 48x4Up to a maximumof 24x8 or 12x16or 6x32 1 DSP for supporting voice ports and Transcodingsessions Remaining 3 DSPs used for ConferencingA maximum of 1Transcoding sessions forthis configurationG.729Up to a maximumof 4x8 or 8x4Up to a maximumof 4x8 or 2x16 or 1 DSP for supporting voice ports and TranscodingsessionsA maximum of 9Transcoding sessions for4FXO2BRI NT/TETranscoding Remaining 2 DSPs used for Conferencing2FXO4FXSCommentsTranscoding 2009 Cisco Systems, Inc.
