ADPCM Card Introduction
Chapter 1
ADPCM Card
1.1 Introduction
This chapter provides installation, configuration, and troubleshooting information for the
Adaptive Differential Pulse-Code Modulation (ADPCM) Card. This card is labeled as the
ADPCM 64 card on its faceplate ejector.
1.2 ADPCM Card Descriptions
1.2.1 ADPCM 64 Card Description (887160)
The ADPCM 64 Card has 32 pairs of voice compression engines that accept inputs directly
from voice, SRU, and/or BRI data cards in the same syst em unit, or voice traffic from WAN
links through the system. This card requires a matching card at the other end to decompress
the voice channels to normal 64 kbps operation.
With prev ious versions of the IMACS, signaling conversi on was only supported for voice
ports when routed over the WAN and not when routed through an ADPCM card. W ith version
5.3.1 and higher of the IMACS host CPU firmwar e, signaling c onversion i s also supported for
voice channels routed thr ough the ADPCM. The conversion table is the same as for passing
the channel t hrough a WAN, and available from the interface card’s main screen by selecti ng
“taBs”. Signaling conversion is enabled / disabled using the same SIG CONV parameter as
used for conversion over a WAN. This field is found on Figure 1-1, the E & M Voice Card’s
main screen .
Each pair of compression engines use s one 64 kbps DS0 time slot for two compr essed voice
channels. Each engine can compress 64 kbps voice traffic into 24 kbps, 32 kbps, or 40 kbps,
depending on the voice signal quality required.
The rate of a DS0 time slot is 64 kbps, so the sum of the compression rates for e ngines 1 and
2 must equal 64 kbps. For example, if you assign a 32 kbps circui t to engine 1, engine 2 can
only accept another 32 kbps circuit. Also, a 40 kbps circuit can only be pa ired with a 24 kbps
circuit, and vice versa.
The ADPCM compression engines always work in pairs. Engines 1 and 2, 3 and 4, 5 and 6,
and 7 and 8 are paired. Each member of the pair must have the same ADPCM WAN port and
ADPCM time slot. Also, both members of the compression engine pair must be active
before either port will operate.

ADPCM Card Descriptions ADPCM Card
The ADPCM 64 Card can transport low-speed asynchronous data transmi ssion (19.2 kbps or
less) from an SRU user card port tha t wil l occupy a 24 k bps engine. Ea ch data circuit must be
paired with a 40 kbps voice channel. The card can also compr ess B-channel voice traf fic from
a BRI card without restricting c ompre ssion rates.
The Integrated Access System can have up to three ADPCM 64 Cards (two normal cards and
an identical redundant card).
The ADPCM 64 Card supports Transi tion Signaling as defined in ANSI T1.302-1989, with
the exception of the Alarm bits. ANSI T1.30 2 specifies signaling at the 32 bps compression
rate. The card us es this sch eme for 24 bps and 40 bps , even thou gh those rates a re not include d
in the standar d. T able 1-1 summarizes the signal s supported by e ach transcod er data ra te. Your
DS0 time slot configuration must adhere to these specifications.

STATE
The State setting de termines whether the port is active or inactive. When assigning ADPCM
engine pairs for WAN traffic, set the State setting to stdby (standby) for port s that are not yet
used or not yet configured. Set it to actv (active) for ports that are ready for use.
Setting the State to rdnt (r edundant) for any p ort on a n unused card will cause th at card to ac t
as the redundant back-up for all of the other ADPCM cards in that unit. Once a card is
designated as a redundant ADPCM card the only way it can be used for regular ADPCM
traffic is to change the state of the selected port back to either actv or stdby.
When assigning ADPCM e ngine pairs from user cards, changing the port from stdby to actv
and saving the selection information on the user card screen will cause the system to
automatically ass ign an ADPCM engine.
When the engine is assigned from a user card, no changes can be made from the ADPCM card
screen to any of the fields.

ADPCM Card ADPCM Card User Screens and Settings
USER
The User setti ng id entifi es the user car d and por t con nect e d to th is eng ine . This is the p lace
where the ADPCM card will expect incoming (non-compressed) voice, subrate data, and
B-channel traf fic. I f assigned fr om a voice, SRU, or BRI card por t, this se lection will s how the
user card slot and port numbe r (e.g., u5-2 for the card in slot U5, port 2). If you are assigning
a WAN time slot, this setting will show n/a.
WAN/SERV
The WAN/SERV setting identifies the incoming WAN link connected to this engine. This is
the place where the ADPCM card will expect incoming (non-compressed) voice. If you are
assigning voice traffic to a WAN time slot, this setting will show w1-1 to w4-2. If you are
assigning to a voice card or SRU card port, this set ting will show n/a.
TS
The Time slot parameter selects the specific time slot of the above WAN link on which the
ADPCM card can expect incoming voice traf f ic. If WAN 1-1 is equipped with a T1 CSU
module or a DSX/CEPT module configured for T1 DSX interface, the options are 1 to 24. If
a DSX/CEPT module is installed on that WAN port and that module is configured for CEPT
E1 interface, the options are 1 to 15 and 17 to 31. If you are assigning time slots to voice or
SRU card ports, this setting will be n/a.
ADPCM W/S
The ADPCM W/S settin g identi fies the o utgoing WAN link to which t he en gine is conne cted.
If you are assigning to a voice, SRU, or BRI card port, or to voice traffic from a WAN time
slot, this setting will show w1-1 through w4-2. This is the WAN link to which the ADPCM
card will send its outgoing (compr essed) traffic.
ADPCM TS
The ADPCM Time slot paramete r selects the spec ific time slot on the WAN link chosen in the
previous settin g that the ADPCM card wil l se nd outgoi ng c ompressed t raf fi c. The opt ions are
determined by the equip ment on the WAN link selecte d in the pre vious setting . If WAN 1-1 is

TYPE
The Type parameter identifies the voice and signaling requ irements for the incoming circuit.
The options are v (voice), voice and v&s (signa ling) and trnsp (transparent). Use v when the
input to the ADPCM channel is a 64 kbps channel and inband signaling is not required. Use
v&s when the input to the ADPCM channel is a 64 kbps voice channel and the ADPCM card
must also provide inband signaling.
The trnsp setting allows you to map the outputs of SRU ports to the ADPCM channel. The
subrate data will be clocke d into t he ADPCM channel at a n input rate of 24 kbps , then pa ssed
transparently (non-compressed) t hrough the ADPCM card to the appropriate WAN time slot.
This could be useful if you have an odd number of voice channels and want to utilize the
empty engine pair of the last ADPCM channel.
The B-channel traffic from the BRI card also uses the trnsp setting, but it does not place any
restrictions on the compression rates.
If the engine is assigned to a voice card, this selection will show v&s. If assigned to an SRU
card, it will show trnsp. You cannot change it from this screen.
RATE
The Rate parameter identifies the compression requirements for the incom ing circuit. The
options are 24K, 32K, and 40K. The sum of the pair of engines must always equal 64 kbps.
If this engine is assi gned to a user car d port, the sele ction wi ll s how the va lue that wa s chosen
on that port. It cannot be changed from this scre en.
SIG MODE
The Signaling Mode parameter identifies the type of signaling required for the incoming
circuit from the network. If v&s was chosen in the Type setting, the options are e&m, fxs,
plar, and fxo. If v or trnsp was chosen in the Type setti ng, the only option is n/a.
If this engine is assigned to a user card, this selection will show user. It cannot be changed
from this screen.
CODING
The Coding parameter identifies the PCM companding format required for the incoming
circuit from the network. The choices are u-law or a-inv.
If this engine is assig ned to a v oice or BRI car d, this se lection will show the value you selec ted
for that por t. If thi s engine is assigned t o an SRU card, thi s selection will show u-law. It cannot

FRS Card
2.1 Introduction
This chapter provides installation, configuration, and troubleshooting information for the
Frame Relay Server (FRS) (881160) card with the 62180 Firmware.
Note that this ca rd is label ed as an ACS card on i ts f aceplate ejector. It is identified as an FRS
card only in the user interface sc reens shown in this chapte r . Throughout the remainde r of this
chapter , it will be referred to as the ACS-FRS card.
2.2 ACS-FRS Card Descriptions
2.2.1 ACS-FRS Card Description (881160)
The ACS-FRS card concentrates multiple N x 56K or N x 64K frame relay da ta streams onto
one or more Nx56/64K links of the Integrated Access System. In addition to frame relay
concentration, the card encapsulates data for Nx56/64K HDLC or SDLC data streams. The
frame relay ser ver sof tware runs o n the card, which provi des up to 68 lo gic al ports. Up to 128
permanent virtual circuits (PVCs) can be configured on a single card. The aggregate speeds
of all ports associated with e ach FRS cannot exceed 8 Mbps.
The maximum frame size supported by the ACS-FRS card is 4,096 bytes p er frame. Each card
can switch 4,000 frames pe r se cond, assum ing a frame siz e of 64 byte s per frame. Up t o three
ACS-FRS cards can be used in a system.
2.2.1.1 Card Jumpers/Switch Settings
The ACS-FRS card does not have any jumpers or switches on its motherboa rd.
2.2.1.2 Installing the Card
Insert the ACS -FR S car d into one o f the serv er card ch as si s slot s (P1 to P3). The sys tem can

2.3.1 ACS-FRS Card Main Screen
You must configure the ACS-FRS card for opera tion after installing it. This is done in the
ACS-FRS Card Main Screen (Figure 2-1). To go to that screen, highlight the desired
ACS-FRS card in the System Main Screen and press <Enter>.
Figure 2-1.Typical ACS-FRS Card Main Screen (ports C1 to C4)
The 68 logical ports of the card are labeled C1 to C4 and 1 to 64. However , numbered ports 1
to 64 do not appear i n the above display . T o se e those por ts, press th e "<" and ">" keys to scrol l
through them, eight a t a time. Figure 2-2 shows a n ACS-FRS card Main Scr een display for the
first eight numbered port s.
The ports C1 to C4 cannot be used for Nx56k, only port 1 to 64 can.
Both the IPR (883060/883160) and the PM-IOR (828060) cards be used with the ACS-FRS
card. The PM-IOR card however, is limit ed to only 14 PVCs per card, wher eas the maximum
number of PVCs available on the IPR card is 128.
When connecting the ACS-FRS card to the IPR or the PM-IOR, one of the 64 ports available
will be used for the communication betwe en the two.
2-2 IMACS System Release 5.1.6 Server Cards
FRS Card ACS-FRS Card User Screens and Settings
The maximum bandwidth possible between the IPR and ACS-FRS cards is 62 time slots
provided on the internal buses “ A” and “B.”
The “C1” and “ C2” por ts o f the F RS ca rd cann ot toge ther be assig ned more t han 32 time slots
due to hardware l imitations. The same is true for the FRS ports “C3” and “C4”. A total of 64
time slots can be assigned all the “C” ports. A similar limitation exists for the ports 1-64
terminating the voice ci rcuits. Each group of 32 ports, 1-32, and 32-64 share a common
internal pipe limite d to 32 time slots each. The maximum number of time slots allows pe r port
is one when all por ts per gr oup is active . If ha lf th e number of ports of a group i s a ctive, twi ce
the number of time slots can be assigned per port.
The maximum internal bandwidth between FRS cards and HSU cards of an Integrated Access
System is limited by the pools size of 126, but also limited by usage from this pool by the
IPR/FRS connections and possible voice card usage.

CONG THRS
The Congestion Thresho ld allows you to select t he amount (in perc entage) that the interna l Tx
queues on the port must be filled before declaring this port is congested (this info rmation is
communicated by FECN and BECN flags). The options are 1 to 100.The default is 95.
Since DE (Discard-Eligibility) frames are not queued to the same extent as non-DE frames,
DE-frames may be dropped when mixed with non-DE frames on the same port before
congestion control is initiated.
T o assure congestion control is initiated even for DE-frames under the conditions mentioned
above, the TX threshold value must be reduced sufficiently to match the percent age
