Standard is the default telephony mode, and it provides standard Bellcore
features, s uc h as u sed i n N o r th A m eri ca.
Users use the flash button or hook flash to transfer, conference and hold calls,
with t he f ollowin g re qu ir ements :
•You cannot use a double hook flash to end a call.

•When putting calls on hold, the first call can be e ither incoming or outgoing.
•When tran sferring a c all or establishing c o nferences, the second call must be
outgoing.

These di fferen t s tat es enable y ou to keep both calls active and s w it ch b etw e en
them. Thus, unlike Standard mode you can keep both calls active for as long as
you want and freely switch between them.
T o transfer or conference, you need to enter the relevant feature code at one of the

Understanding Caller ID Support
If you have activated caller ID on Cisco CallManager, the VG248 can collect that
informat io n and pa ss it on to an alog ph on es. You can d isable ca ll er I D on a per
port basis. This enables you to support caller ID on some analog phones and not
on others (see the “Enabling Caller ID” section on page 3-11 for details).
The VG248 supports the following caller ID standards:
•Bellco re G R- 3 0- CORE—North Am er ica
•ETS 300 648 and ETS 300 659-1—Europe (excluding the United Kingdom)
•British Telecom SIN227 and SIN 242—United Kingdom

Supported Analog Devices
When a call ar r ives, th e VG 2 48 s en d s th e fo ll owing i nf o rm ati on :
•Time and date in form atio n
•Calling number up to 18 digits when available, otherwise the reason why
number i s u navaila bl e
•Callin g n ame up to 2 0 ch ar act er s w h en availab le
Supported Analog Devices
The VG248 has a maximum ringer equivalency number (REN) load of three (3)
analog devices per line (using a shared directory number), and only two of these
devices can be off-hook at any one time.
You should use analog devices designed to work in the country in which you are
using the VG248. For example, if you are using the VG248 in the United
Kingdom, you should use analog devices designed for use in that country.

Speakerphones
The VG248 pe rforms line ec ho cancel lat ion, bu t it does not perfor m acoust ic echo
cancell ati on . S p ea ker p hones wi th bui lt -in ech o cance ll ati on su ch as the
Polycom-brand phones should work fine. However the voice quality might be
unsatisfactory when using a speakerphone that does not perform acoustic echo
cancell ati on i tself.
Private Line Automatic Ringdown Phones
A telephon e conf igur ed as a Pri va te Line Auto matic Rin gdo wn (PLAR) telepho ne
dials a pre-configured number when it goes off-hook. You cannot use PLAR
phones to dial any other numbers. Telephones in hotel lobbies and airports are
often configured in this way.
Supported Analog Devices
Fax Machines
Modems
Cisco CallManager release 3.0 and later can be configured to support the PLAR
phone fe atu re for a n IP pho ne or for an a nalo g tel ep hone c onnec ted to t he VG2 48.
The V G248 supp orts fax m achines in pass-through and Cisco fax relay modes. In
fax pass-through mode, the gateways do not distinguish a fax call from a voice
call. Cisco fax relay offers a more reliable way of transporting the fax data in
order to increase the data rate. However, the terminating gateway must also
support Cisco fax relay. If necessary, you can disable Cisco fax relay (see the
“Disabling Cisco Fax Relay” section on page 3-3 for details) .
The VG248 supports modems in pass-through mode.

Integrating Cisco CallManager with
Voice Mail Systems Using SMDI
Simplified Message Desk Interface (SMDI) defines how phone system s provide
voice mail systems with the information needed to intelligently process incoming
calls. It is an industry-s tandard signaling protocol that supplies calling and called
party identification and sets and clears Message Waiting Indicators (MWIs)
through an RS-232 serial connection.
Using SMDI and the VG248, you can integrate your existing voice mail systems
(such as Lyrix, Octel 200, Octel 250, Octel 300 and Octel 350) and legacy PBX
systems with Cisco CallManager.

Assigning Number of SMDI Ports
By default, none of the ports on the VG248 are configured to send SMDI
informa tion abou t calls made to those ports. To enable SMDI, you mus t assign the
number of SMDI ports a value from 1 to 48. Using fewer than 48 ports for SMDI
means th at th e r emainin g p or ts can b e u s ed f o r co nnect in g analog p ho n es ,
modems, or fax machines.
If you us e fewer than 48 p orts for S MDI, yo u must en sure th at the SMDI po rts are
consecutive ports beginning with port 1. For example, if this valu e is set to “10”,

Identifying the First Voice Mail Port Number
With a singl e V G2 4 8 co nnected t o a vo ice ma i l syst em ( su ch as in th e basic
configuration), port 1 on the VG248 should be connected to port 1 of the voice
mail system, and similarly for the other VG248 ports.
However, with m u lt ip le VG 248 devices co n ne cted to a singl e vo ice ma il s yst em
(suc h as in the c hain ed conf i gura tio n) t hi s sim ple m appi ng i s poss i ble on ly on th e

mail port numbers.
Using this se tt in g, you ca n iden tif y th e fir st port used o n t h e vo ice mai l s yst em .
This value should correspond to the port number on the voice mail system to
which po rt 1 is conn ected . In all case s, conn ectio ns from a sin gle VG248 must use

Configuring SMDI Settings on the VG248
For example, if two VG248 devices are connected to a 96 port voice mail system,
one VG248 connects to ports 1-48, and the other connects to ports 49-96. On the
firs t VG24 8 device, set the First voice mail port number to 1 (the default va lue)
and set the value to 49 on the second VG248.
As ano th er exa mpl e, if 8 0 voi ce mail p orts were i n use an d tw o V G 248 devi ces
were each providing 40 ports, the Number of SMDI ports on each VG24 8 w oul d

Setting SMDI Number Length
Tr aditio nal SMDI incl udes cal ler and called party in format ion as 7- digi t number s.
If the number is shorter than 7 digits, extra digits (typically zeros) are added to
the left. For example, the extension number “12345” becomes “0012345” when
sent via SMDI. However, because 7 digits are not enough for external caller ID,
an extended SMD I fo rmat is avail abl e t h at uses 10 - di g it nu mb er s .
Most voice mail systems are flexible, supporting either SMDI f ormat. However,
some older systems insist on receiving exactly seven digits. Check the voice mail
system’s doc umentat ion to d etermin e w h ich se tt in g is most ap propri ate.
You can set the VG248 to output using either 7- or 10-digit numbers. It should
match the value required by you r voice ma il system. You c an also set the number
length to <unpadded>, which indicates that the voice mail box numbers are
always passed unmodified between Cisco CallManager and the analog voice mail
system.

Allowing SMDI Number to be Truncated
If SMDI extension numbers are longer than the traditional 7 or 10 digits, the
VG248 can either pass on the entire number or truncate the extension number to
the length you defined in the SMDI number length. If you have set the SMDI number length to unp a d de d, this sett in g has no effe ct.

Suspending SMDI Port Activity
If you are using the chained configuration and want to temporarily remove one of
the VG248 devices or upgrade software on it, you should suspend activity on the
SMDI ports before shutting down or restarting the VG248.
By suspending activity, the VG248 waits for the port to become idle, then it
tempor ar il y removes the p or t fro m C isco Cal lM an ag er and su sp en ds the por t ,
preventing any activity on it. Once all the ports have been suspended, traffic from
Aysnc 1 is also suspended on the device. SMDI traffic from Async 2 from the
previous VG248 device in the chain queues up while this device is suspended.
Suspending the device does not affect whether ports are enabled or not; if they
were e na bled b ef or e b ei n g su sp en de d, th ey ar e en ab l ed af ter b ei ng r es u me d.
