Product Overview
The Cisco®Unified Communications 540 (Figure 1) part of the Cisco Unified Communications 500 Series for Small
Business, is a critical part of the Cisco Smart Business Communications System. It is an affordable unified
communications appliance that provides voice, data, voicemail, automated attendant, video, security, and wireless
capabilities while integrating with existing desktop applications such as calendar, email, and customer relationship
management (CRM) programs. This easy-to-manage platform supports up to 32 phones and voice mailboxes and
provides flexible deployment options based on your needs, including support for a wide array of IP phones, public
switched telephone network (PSTN) interfaces, and Internet connectivity. This reference guide describes the
specifications and capabilities of the Cisco Unified Communications 540 (UC 540).

Product Part Numbers
The 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 licensing
product, multiples of which can be installed to achieve the desired user count. Table 1 lists the part numbers for the
Cisco UC 540.

WLAN interface An 802.11b/g access point is integrated into the UC 540, supporting up to 54-Mbps
connections. The access point can be used to provide integrated WLAN connectivity to mobile
clients—voice and data—resulting in mobility and enhanced productivity for users.

Licensing
The Cisco UC 540 includes eight user licenses. These licenses enable the use of Cisco Unified IP Phones and allow
users to access the IP PBX features, including voicemail. In addition, supplementary user licenses are bundled to
help with deployments that need a few extra licenses. For additional licensing needs, the L-UC-PRO-8U= may be
ordered. This increases the existing license count by eight. Table 5 lists the number of users supported based on the
hardware/license configurations. The UC 540 also has built-in licenses for unified communications features. Table 4
lists the license count bundled within the system for each feature. Guidance for licenses associated with voice
messaging on the UC 540 is included in Table 6.

Internet Message Access Protocol (IMAP) sessions 20**
* 32 hours of voicemail storage is available by default across all user configurations. Any combination of personal mailboxes and
general delivery mailboxes can be used.
** There are 20 simultaneous sessions available between IMAP Client and IMAP server. If all 20 sessions are used up, the
remaining session requests will be rejected by the IMAP server. IMAP clients will automatically attempt to establish session with the
server once some of the server ports are freed up. This does not limit the number of IMAP clients to 20.
Basic Call Center Capabilities
The Cisco UC 540 supports basic automatic call distribution (BACD) that can help answer outside calls with
greetings and menus and allow callers to select the appropriate departments. BACD also provides managed call
queues for calls that are waiting to be answered. Table 7 lists the BACD capabilities of the UC 540.
Table 7. Cisco UC 540 BACD Capabilities
Feature Number
Hunt groups associated with a BACD 10
Calls allowed in each call queue 30
Agents (members) for each hunt group 20
Statistics accumulated for all BACD groups 168 hours
Hunt groups used with automated attendant 3
In addition to BACD, the Cisco UC 540 integrates with Cisco Unified Contact Center Express (UCCX). UCCX works
with up to a maximum of 12 users (agents and supervisor combined) on the UC 540.
Voice Resource Utilization
The Cisco UC 540 includes four digital signal processors (DSPs) that enable digitized voice processing on the
platform. The DSP resources available on the platform are used for various unified communications features, namely
support of analog and digital VICs, prescheduled or ad hoc voice conference calls, and translation of digitized voice
from a less complex codec (such as g711) to a more complex codec (such as g729)—typically used for deployments
that 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 Cisco
UC 540. Table 8 indicates the DSP resource utilization based on the feature. Tables 9 and 10 show a few
deployment scenarios based on the combination of these features.

Table 8. DSP Resource Utilization on the Cisco UC 540
Feature DSP Resource Utilization
Support for built-in FXS ports 4 channels
Support for built-in FXO ports 4 channels
Support for built-in music on hold (MoH) port 2 channels
Support for T1/E1 voice/WAN interface card (VWIC) 24 channels*
Transcoding (g711 to g729) 2 channels
Conferencing** 16 channels
* Total DSP resources will depend upon the number of channels provisioned in the T1.
** Conferencing always uses up an entire DSP. The rest of the features can share a DSP. The number of sessions available will
vary 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 resources
allocated for conferencing can be shared by both features, and a mix of these can be configured. Below are a few
examples based on Table 9. The concept of sharing conferencing resources applies to Table 10 as well.
Ad hoc 24x8 Meet-me 0x0
Ad hoc 12x8 Meet-me 12x8
Ad hoc 24x4 Meet-me 6x16
The above examples indicate Sessions x participant.
The Transcoding column lists the maximum transcoding sessions that the system can be configured for, for a given
configuration of DSP. For example, the first row in Table 9 indicates that a maximum of three transcoding sessions
are 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 for
conferencing. Notice the increase in the number of transcoding sessions and the drop in the number of conferencing
sessions.
