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.

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 equipped with an 812 CSU or 81 1 DSX/CEPT Module configured f or DSX, the optio ns are 1 to 24. If a DSX/CEP T module is instal led and configured for CEP T E1, the options are 1 to 15 and 17 to 31.

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 be changed from this screen.

Chapter 2 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 accommo dat e up t o three s erv er cards .

2.3 ACS-FRS Ca rd User Screens and Settings

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.

STATE

The State setti ng determ ines whe ther the port i s acti ve or inac tive. Set the Sta te fie ld to stdby (standby) for por ts you are not using or have not yet configured. Or, set it to actv (active) for ports that are ready for use.

WAN/SRV

The WAN setting identifies the WAN link assigne d to this port. You do not have to a ssign all ports on the same card to the same WAN link. You also don’t have to assign card ports to contiguous time slots of a WAN link. The default value is none.

The Time Slot setting identifies the time slots on the WAN link when wan is selected in the previous setting. The ACS-FRS card can use many (up to 24 T1 or 31 E1) time slots on a single WAN port, in order to create a super-ra te circuit for an individual FRS port. One or all time slots of a T1 or E1 lin k can be a ssembled for use by the FRS po rt, ac cording to th e s peed requirements of the DTE.

You can assign time slots by pressing <Enter> and using the space bar to select and deselect the required number of time slots. These assignments do not have to be contiguous.

RATE

The Rate setting allows you to adjust the speed of the ci rcuit according to the application requirements. The only speed availab le for ports C1to C4 is 64k (64 kbps). Howe ver, ports 1 to 64 can be set to either 56k or 64k.

• Error Threshold (N392)

• Poll Verify Timer (T391)

• Events Counter (N393)

The Error Threshold (N392) counts the err ors that will be toler ated during the cast number of events as set by t he Events Counter b efore declaring th e LMI link down. The number of error s options are 1 to 10. The value is input using the keyboard of the contr ol terminal. The default is 3.

The Poll Verify Timer (T391) allows you to select the time interval (in seconds) that should elapse between “keep alive” messages sent from the corresponding DTE. The number of seconds options are 5 to 30. The default is 15 seconds.

The Events Counter (N393) allows you to sele ct the window size for the number of events (frames) in which errors will be counted. If error threshold (N392) is exceeded within cast N393 frames, th e link is declared down. The number of events count ed are 1 to 10. The default is 4.

BC(Kb)

The Bits Committed setting defines the threshold for the transmit rate (outgoing frames) where the card will make every effort to deliver the traffic to the subscriber. The time used to average rate is determined by the card by dividing the Committ ed Information Rate (CIR) by Bc. The number input must be between 0 and 2048.

BE(Kb)

The Bits Excessive setting defi nes the threshold for the transmit rate (outgoing frames) where the carrier will admit the frames into the network (in effect, this is the maximum transmission rate). Frames sent below this threshold but above the BC (KB) threshold are admitted into the carrier network with the DE (discard eligibility) bit set. If congestion occurs in the network, these frames are the first to be discarded. The options are 0 to 2048.

2.5 ACS-FRS Card Troubleshooting

Problems with a FRS card could indicate a number of causes. Some possibilities are:

• T1 or E1 network failure

• Improper frame relay network configuration

• Improper FRS card configuration

• Improper user card configuration

• Faulty cabling between the DTE and user card

• Improper DTE configuration

T ypically, a problem is indicated by the inability to send or receive frame relay traf fic through the FRS card. There are numerous ways of isolating and clearing the problem. When troubleshooting frame relay communications problems through an FRS card, follow this general sequence:

1. If all Frame Relay traffic is affected, verify that the US/EUR jumper is correctly placed to match the US/ EU R j ump er o n the ch ass is. The FR S card performs a self- te st on power-up. A “healthy” card will have a green LED lit on the front panel. Do not proceed with further st eps until a green LED is present.

2. V erif y that the T1 or E1 network is working properly by checking for current CGA-Red and CGA-Yellow alarms (see Chapter 3-A for alarm viewing instructions). If no CGA alarms are present that would affect the frame relay traffic, continue with step 3.

3. Verify that the FRS port is connected to the proper WAN card and time slot or user c ard port and that the correct type of LMI is selected. If a user card port is used, verify the configuration settings on the user card port and the cable connection to the DTE. The LMI must be UP for data to f low on the circuit . Do not proceed with f urther steps unt il the LMI is up.

ACS-FRS Server Card Specifications FRS Card

4. Go to the Port Performance Monitoring Screen by pressing P from the FR S Main

Screen. Analyze the regist er and status information provided to help deter mine the cause of the problem.

5. Go to the Circuit s Sc ree n of the FR S car d (whi ch can be acce ssed by selec tin g Circ from the FRS Main Screen). Verify that the affected circuit STATUS is up (indicated by a “U”). If it is not up, this may indicate that an LMI is down in the far end of the circuit. Highlight the affected circuit and typ e P and the performanc e regi ster s for the circuit will appear . Analyze the informati on provided to help determine the c ause of the problem.

6. Loopbacks are available on the “C” ports only . If a “C” port with an LMI is looped back toward itself, the PORT TYPE must be nni for the loopback to functi on.

7. If the FRS card is determined to be faulty , replace it and return the faulty unit for repair to the location specif ied by your distributor .

MCC Card Introduction

Chapter 3 MCC Card

3.1 Introduction

This chapter provides installation, configuration, and troubleshooting information for the Management Channel Concentra tor (MCC) card.

Note that this card is labeled as an ACS card on its faceplate ejector, and it is called an ACS-MCC card only in the user interface screens described in this chapter. Throughout this chapter, it is referred to as the ACS -MCC card.

3.2 ACS-MCC Card Descriptions

3.2.1 ACS-MCC Card Description (881360)

The ACS-MCC card uses 63 1xx MCC fi rmware a nd all ows you to manage r emot e Integra ted Access Systems by using TCP/IP or SNMP/UDP/IP communicat ion protocols. The control link to each rem ote system can be the FDL (Facilit y Data Link) bits of an ESF-fra med T1 line. Or, for an E1 line, this lin k can use the SA4 bit s in the f rame ali gnment words of the E1 signal. Full time slot B7R requir es a DACSII 6.1 or equivale nt. MCC does n’t talk dir ect to FDL l ink,

this requires a DACs to convert full time slot B7R to B4R.

The ACS-MCC card incorpo rates four Munich32 chips (two on the main board and two on a daughterboard). which allow up to 128 WAN interfaces. The ACS-MCC card also supports three configurable high-speed ports (C1, C2, and C3), plus an Ethernet 10Base-T port for LAN routing management.

The MCC can route IP datagrams between all of its interfaces, based on each datagrams IP destination address. Datagrams are directed (or routed) to the interface carrying the sub-net to which the datagram belo ngs or is being tr ansporte d to, acc ording to the content of the routing table. The routing table may be supplied with dynamic routes from the Routing Information Protocol (RIP) when enabled. If no match is found in the routing table, a default route can be designated to direct all unresolved datagrams to a specific interface.

Figure 3-1 shows the role of the ACS-MCC card in a Network Management System. Both SNMP alarm traps and TELNET configurations run over this path . They can use the FDL (T1 line), the S line.

If the FDL is used to transmit and receive inform ation, a DACSII (6.1 or higher) must be used to convert the FDL/IP information into DS0. On point-to-point circuits, the DACSII is not needed. The MCC can also be used to create larger “trees” in which the high-speed ports (C1, C2, and C3) can interconnect the d ifferen t AC S-M CC cards in the hiera rch y.

STATE

The State setting determines whether the port is active or inactive. Set the State to stdby (standby) to disable the Ethernet port, or choose actv (active) to enable t he port.

IPADDR

When configured for unnumbered interfaces, the IP Address setting identifies the global IP Address of the MCC. This address is thus valid regar dless of the state of the Ethernet port. When configured for numbered interfa ces, the IP address of the Ethernet port ide ntifies the IP address of the E ther net inte rfa ce o nly.

3-4 IMACS System Release 5.1.6 Server Cards

MCC Card ACS-MCC Card User Screens and Settings

NETMASK

The IPADDR together with the NETMASK identifie s the IP network for the Ethernet interface. Any valid netmask ad dress is acceptable.

DEF RT

The Default Route setting ide ntifies the IP Address of the port used to forward IP datagrams with destination unknown to the MCC. When stat (static) is selected, the IP address must be entered by the user. When dyn (dynamic) is selected, the IP address is dynamically assigned by a router. RIP must be turned on if dyn is selected. The de faul t is none.

RIP

When the Routing In formation Protoc ol (RIP) setting is off (default), no RIP traffic is allowed into or out of the Ethernet interface. Setting this variable to rx allows incoming RIP traffic only, while setting it to tx allows only outgoing RIP traffic. Setting this variable to rx/tx allows both incoming and outgoing RIP traffic.

Note: Due to the high number of interfaces on the ACS-MCC card and the relatively low

bandwidth of the Munich interfaces, you should be careful when implementing the RIP option.

When the Split Horizon (SH) variable is set to on, the ACS-MCC card does not automatically send RIP information along routes it “learned” through the same interface. The default is off.

The Weight parameter assigns a weighting variable to the specified interface. The number must be between 1 and 15. The default is 1.

FMT-MAIN

This parameter is used to indicate the format of the 64 ports on the main board. When bxr is selected, ports 1 through 64 are configured to B4R (E1) or B7R (T1). When hdlc is selected, ports 1 through 64 are configured to 64 kbps. (See note below for exception.)

FMT-SUB

This parameter is used to indica te the format of the 64 ports on the sub-board. When bxr is selected, ports 65 th rough 128 are configured to B4R (E1) or B7R (T1). When hdlc is selected, ports 65 through 128 are configured to 64 kbps. (See note below for exception.)

Note: The only invalid configuration for FMT- MAIN and FMT-SUB occurs when

FMT-MAIN = bxr and FMT-SUB = hdlc. This configuration is not supported.

IF-TYPE

The IF-TYPE parameter determines the IP addressing scheme to be used by all interfaces (except the Ethernet int erface, which is always numbered). The default option is unnum, which causes the interfac es to be unnumbered. When configured in this manner, the MCC is addressed through the global IP address of the Ethernet inte rface, re gardless of the origi nating interface, and the IP address of all interfaces (except the Ethernet interfa ce) is determined by the interface on the remote en d. Selectin g unnum may help conserve IP addres s, but may not be compliant with the HP OpenView network management system.

The num option allows for numbered interfaces. When this option is selected, each int erface is assigned a local IP addre ss on the same network as (but differ en t from) the remote device. Two broadcast IP addresses are also reserved for each interface, for a total of four IP addresses per port. Numbered interfaces are industry-standard, and are compliant with the HP OpenView network management system.

Setting this variable to rx allows incoming RIP traf fic only , while setting i t to tx allows only outgoing RIP tr affi c. Setting this vari able to rx/ tx allows both incoming and outgoing RIP traffic.

Note: Due to the high number of interfaces on the ACS-MCC card and the relatively low

bandwidth of the Munich interf aces, the user should be cautio us about implementing the RIP option, as there is a substantial risk of broadcast storms causing congestion in the network.

When the Split Horizon (SH) variable is set to on, the ACS-MCC card does not automatically send RIP information along routes it “learned” through the same interface. The default is off.

3.6 AC S- MCC Car d Tr oubles hooting

MCC card problems could indicate a number of possi ble causes, including:

• Misconfigured IP parameter at the far end

• Faulty cabling between the MCC LAN port and the LAN

• T1 or E1 network failure

• Improper network configurati on

• Improper MCC card configuration

Typically, a problem is indicated by the inability to route IP traffic to/from or through the MCC card. You can perform numerous tasks to isolate the trouble and clear it. When troubleshooting problems on IP communications through an MCC card, follow this general sequence:

1. If all IP traffic is affected, verify that the US/EUR jumper is corre ctly placed to match the US/EUR jum p er on the chassi s . Th e MC C card perfo r ms a self- te st on po w er-up. A “healthy” card will have a green LED lit on the front panel. Do not pr oceed with further steps until a gre en LED is present.

2. V erify that the Ethernet Port (E) is actv and that the correct IP address (IPADDR) and NETMASK have been entered. At this point, attempt to “ping” (from the CPU card TCP/IP screen) the IP address of the MCC Ethernet por t from another device on the LAN. Pressing N from this screen will display the Network Statistic registers for the Ethernet port. Analyze the information to determine the cause of the failure. Do not proceed with further st eps until this ping is successful.

3. From the CPU Main Menu screen, go to the TCP/IP screen by pressing I. Verify that the options and addresses on the TCP/IP screen are correct. Press “P” (for ping) and enter the IP address of the MCC card Ethernet port.

4. If Step 3 is not successful, verify that the DE FAULT IP PORT is set to serv and that the DEF AULT IP SLOT is set to the chassis slot in which the MCC card reside s (P1, P2, or P3). At this point, attempt to ping the card again by pressing P. Do not proceed until this ping is successful.

5. V erif y that the T1 or E1 network is working properly by checking for current CGA-Red and CGA-Yellow alarms. If no CGA alarms are p resen t that w o uld affect IP traffic, continue with step 6.

3-16 IMACS System Release 5.1.6 Server Cards

MCC Card ACS-MCC Card Troubleshooting

6. Verify the configuration settings for the affected MCC port. Be sure the port is

connected to the proper WAN card and port, that the correct FORMAT is selected and that the appropria te IP address (IPADDR) and NETMASK have been entered. If these assignments ap pear correct, go b ack to the CPU TCP/IP menu and ping the addr ess of the remote device connected to that MCC port. If this is not successful, ping back toward the MC C ca rd from the remote devic e. Pr ess ing N from the MCC card Port screen will dis play the Network S tatistic regi sters for th e port. Analyz e the information to help determine the cause of the fail ur e. The problem may be either in the network between the MCC port a nd the remote devi ce, or i ncorrect IP address ing/configur atio n of the remote device.

7. If the MCC card is determined to be faulty, replace it and return the faulty unit for repair to the location specif ied by your distributor .

ACS-PRI/BRI Card Introduction

Chapter 4 ACS-PRI/BRI Card

4.1 Introduction

The ACS-PRI/BRI server card (881162) uses 651xx firmware and offers users the ability to effective ly terminate and manage both dedicated and switched carrier services in a single system. This capability allows users to pick the most cost-eff ective services for both permanent connections (e.g., LAN-to-WAN) and periodic connections (e.g., video conferencing). In addition it also enables originating an d receiving calls to BRI cards.

Three specific features enable the system to use ACS-PRI/BRI services, and are covered in this chapter. These features are:

• ACS-PRI/BRI server card

• Call profiles (accessed from the Interface Card)

• HSU-AD 530/35 switched services data card

The switched services HSU card information is repeated in the chapter on HSU cards, and the call profile information is repeated in the Interface Card chapter.

4.1.1 Definitions

4.1.1.1 Timeslot

Each T1 or E1 WAN link accessed by the system is subdivided into individual 64 kbps channels calle d timeslots ( T1 has 24 timesl ots, E1 has 32 ). A timeslot is sometimes also called a DS0 or a B (bearer) chan ne l. W hile al l three t erm s refer t o the sam e co ncept, this manua l will assign arbitrar y definitions to distinguish timeslots controlled by ISDN from those that are not.

4.1.1.2 DS0

A DS0 is a timeslot on any W AN lin k that is not controll ed b y an ISDN si gnalin g cha nnel (the D chann el). Thus, DS0s are controlled via assigning user ports to WAN timeslots (see

individual use r card c hapte rs) a nd via settin g up cross-c onnect c ircuits ( see Chapte r 4, System Configuration and Operation in the System Reference Guide).

Server Cards IMACS System Release 5.1.6 4-1

Running Head

Introduction ACS-PRI/BRI Card

Model No.

4.1.1.3 B Channel

A B channel is a timeslot on any WAN link that is controlled by an ISDN D channel. B

channel assignments to WAN links are used dynamically by the system as incoming and outgoing ISDN calls occur.

In the syst em, e very timeslot is either a B channel or a DS0. Users can define which is which via the D channel configuration screen described later in this chapter.

4.1.1.4 D Channel

A D c hannel carries signaling information for all B channels with which it is associated. Each D channel occupies an entire times lot which is dedicated to ISDN signaling. The D channel can also be used to log into a remote system unit (see later in this chapter).

4.1.1.5 Facility

A facility is another term for an indi vidual T1 or E1 WAN link.

4.1.1.6 Interface

The term “interface” is used inte r changeably with facility when referr ing to an ISDN link.

4.1.1.7 NFAS (Non-Facility Associated Signaling)

A basic ACS-PRI/BRI facility is a T1 link that consists of 23 B channels and 1 D channel (23B+D), or an E1 link that consists of 30 B channels and 1 D channel (30B+D). Note that one timeslot on any E1 link is reserved for maintenance use and is neither a B channel nor a D channel. The D c hannel provid es signali ng for all (23 or 30) of the B channe ls on th e facility carrying the D channel.

However, many ISDN applications have relatively low call rates (i.e., the D channel is not very busy), but need more than 23 (or 30) B channels to carry user (bearer) traffic. In these cases, a D channel can be set up to perform signaling not only for the B channels on its own facility, but also for B channels on other facilities (i.e., oth er T1/E1 WAN links). When a D channel is s o provi sione d, i t is consider ed to be pe rf orming n on-facility associa ted signaling (NFAS).

Some carriers’ impleme ntations of NFAS allow one D channel to carry signaling for up to 20 facilities (i.e. , 479 B channels and 1 D channel in a T1 environment). However , the system is limited to 8 WAN links. Thus, the system limit for NFAS is 191B+D in T1 environments (8 times 24 minus 1 D channel), and 239B+D in E1 environments (8 times 30 minus 1).

4-2 IMACS System Release 5.1.6 Server Cards

ACS-PRI/BRI Card Introduction

4.1.1.8 Trunks

An ISDN trunk is a logic al d ivisi on of B channe ls pertaini ng t o a D cha nnel. It consi sts of one or more contiguous or non-conti guous B channels. All B channels in a trunk must belong to the same D channel. However, a trunk may be assigned across differe nt physical interfaces when NFAS is used.

4.1.2 Selecting D Channels , B Chann els, an d DS0s

The D channel configuration screen s described later in this chapter show how to configur e D channels, assign B channels to one or more D channels, and how to identify dedicated DS0s that cannot be used as B channe ls. This section will give a few examples of applications that would require various combinations of D channel(s), B channels, and DS0s.

Figure 4-1 shows an a pplication where a single D channel performs ISDN signa ling for 8 T1’s worth of B channels (191 B+D). There are actually 8 sep arate T1 facilities: seven with 24 B channels each, and one with 23 B channels and one D channel.

4.1.3 Network and User Side Protocols

In the example application shown in Figure 4-3, there is an important difference between the two D channels terminating in the carrier switches and the D channel terminating in the user’ s PBX. The ISDN signaling protocol that runs on the D channel is not symmetrical. Signaling messages are treated differently depending on whether the D channel is setup to run the network side protocol or the user side protocol. All carrier switches run the networ k side protocol, and all user devices connected directly to a network switch must run the user side protocol. In general, network side applications cannot be connect ed to other network side applications. Local routing, the exception to this rule, is explained in the next section.

Figure 4-4 shows how the application in Figure 4-3 would be set up if the user’s PBX was not connected to the system.

The disadvantage of this conf iguration is that the PBX may not be able to support two D channels, may not be able to handle the differences in D channel protocols betwee n the two carriers, and may not be able to route calls to the appropriate carrier.

Figure 4-5 highlig hts the ability of the system to be a ble to set the protocol between networ k side and user sid e for each D chan ne l it uses . Sin ce the PBX can onl y ru n th e user side protocol, the system must run the network side protocol on the D channel connected to the PBX. However, on the D channels connected to the carrier switches, the system must run the user side protocol.

4.1.4 Call Routing

The system c an be simultaneously connected to seve ral network and user side ACS-PRI/BRI facilities and to a user’s data terminal equipment (DTE) such as a video codec or a LAN router . The DTE is typically connected through one or more of the system’s HSU cards.

4.1.4.1 Calls Originating from an HSU Port

Any call originat ing from an HSU port must be a ssociated with a c all profile (see Call Profile s section). The call profile specifies which D channel is to carry the call. The system will always route an outgoing HSU call to B channels controlled by the D channel specified in the call profile. If no B chann e ls are av ail ab le, the cal l will not be plac ed .

4.1.4.2 Calls Destined to an HSU Port

Each HSU port in the system that is available to receive incoming calls must be assigned a unique primary phone number that allows the system to route an incoming call to it (see the Dial screen in the HSU section). Optionally, a hunt group phone number (which need not be unique) can also be assigned to the same HSU port.

When an incoming cal l is received by the system, it first scans all of the primary HSU phone numbers to attempt a match. If a match occurs, the call is routed to that HSU port. If no match is found, the system then searc hes the list of hunt group number s to find a match. The call will be routed to the first HSU port with a matching hunt group phone number.

If a match is st ill not found, the system begins searching t he D channel rout ing tables (see next section). If no match is found after all searches are finished, the system rejects the incoming call.

4.1.4.3 Calls Originating from a D Channel

All calls originating from a D channel are considered incoming calls to the system because the system is first made aware of the call when an incoming call message is received on the originating D channel.

As described above, the system fir st tries to route any incoming call from a D channel to an HSU port. If it c annot mat ch the calle d nu mber to an HSU port prim ary numb er or hunt group number, the system begins looking in the D channel routing tables (see Assignment of Call Routing Informati on later in this chapter). It will route the cal l to the first D channel it matc hes. If no D channel routing informat ion matc hes, the call is rejected. As are used as “wildca r ds” that will allow any number in its place to match. It is recommended that one ca rr i er D

channel be assign ed the d efault r outin g code of “xxx-xx x-xxxx” so that t here will always be a match.

ACS-PRI/BRI Card Introduction

4.1.5 ISDN Tr unks

An ISDN trunk is a logical division of B channels pertaining to the same D channel. A D channel can ha ve one or more t runks. Trunks cannot be used for local routing, so unless the user has more than one D channel, trunks will not apply to their system. The basic rules for trunk assignment are:

• A single B channel cannot belong to multiple trunks simultaneously

• The maximum number of trunks that c an be assign ed to a si ngle D channe l is 15 (labe led

trunk “A” through trunk “O”)

• B channels in a trunk can be contiguous or noncontiguous

• A trunk cannot cross D channel borders, but can span diff erent WAN links when NFAS

is used by the carrier.

After ISDN tr unks are configured, users can designate a routing table where incoming trunks can be routed to outgoing trunks. The routing table can be constructed to specify up to three outgoing trunk paths for each inc oming trunk.

The basic rules for trunk routing are:

• Each incoming trunk can be routed to up to three outgoing trunks which are prioritized

into search patterns 1, 2 or 3

• The D channel of the incoming trunk must be different from that of the outgoing trunk

• A trunk can be used as an outgoing trunk for more than one incoming trunks

• All trunks must be configured before assigning them to a routing table.

4.1.6 Local Routin g

Devices such as vi deo codecs or PBXs that are directly a ttached to the system ( i.e., do not pass through a carrier network to connect to the system) are considered “local” devices . All HSU ports are local devices. In addition, any PRI device such as a PBX that is connected to a D channel configur ed for network side is a l ocal devic e (as expla ined in the previou s section , any D channel connected to a carrier network must be configured for user side).

Local routing is define d as call routing between any two local de vices. Because each HSU port can be mapped by its call profile to any specific D channel (local or non-local), users can prevent local routin g of call s originating from any HSU port by insuring that the call profile refers to a user side (i.e. , non- local) D channel.

However, calls coming into the system on a D channel (user or net work) are routed based on the called phone number, not on call profiles. Because the system does not provide billing information, users may want to prohibit local routing of D channels. This prohibition will force all incoming D channel call s (user or network) to be routed to a carrier networ k so billing information ca n be obtained. In ot her cases, however, users may want to enable local routing.

Server Cards IMACS System Release 5.1.6 4-9

Running Head

Introduction ACS-PRI/BRI Card

Model No.

Thus, if local routing is disabl ed, any call coming into the system on a network side (i.e., loca l) D channel will be routed only to a user side D channel based on the calle d number . Even if the called number matches, such a call will never be routed to an HSU port or a network side D channel when local routing is disa bled.

If local routing is enable d, then any call coming in on a D channel will be routed to the first matching phone number, regardless of whether or not the match is for a local device.

Figure 4-6 shows a system connected to two carriers (A and B), two ISDN PBXs, two video codecs (#1 and #2) and a LAN router. The examples that follow help explain the call routing parameters.

• A call from PBX #1 to 800-444- 2095 will be routed to PBX #2 if local rout ing is en abled,

but will be routed to Carrier B if local routing is disabled.

4.1.7 Call Profiles

A call profile is sim ilar to a speed dial button on a te lephone or fax machine. The user enters call profil e s o n the Int erface Card and st o r e s th em in th e sys tem’s mem o r y. The maximum number of call profiles i s six. These stored call profiles can be recalled from memory, copied to the HSU port memory, and used by that port to dial a call. The same call profile may be copied in the dialing memory of multipl e HSU ports.

For ISDN calls, call profiles specify t he D channel to use, the number to call, the data rat e of the call, the service to use, and other pertinent information required to place the call.

Before any HSU port can dial a call, it must load a call profile from the main system memory into its own dialing memory. The HSU port can use the call profile “as is” or chang e the various paramete rs depending upon the calling needs. The loaded profile, including changes, will remain assoc iated with the HSU port unt il another ca ll profile i s copied fr om the Interfa ce card.

STATE

The State setting determines the stat us o f each D cha nne l. The av ail ab le o ptio n s are stdby, conf or actv.

As with most other cards in the system, the stdby (sta ndby) setting keeps the resource to which it is associat ed (in this case, the as s oci at ed D chan nel ) i n inact i ve mo de. W hen a D channel is in stdby, it does not use a ny syste m r esources su ch as B ch annels or proc essor ti me on the ACS-PRI/BRI server card.

fjtsu

When a D channel is in actv (ac tive) stat e, all B chan nels ar e rese rved, and t he syst em att empts to maintain its D channel se ssion with the other end (e.g. swi tch or PBX) of the D channel. If the D channel loses contact with the other end when it is in the active state, a D channel alarm will be generated.

Because there are times when users want to temporarily suspend the D channel session with the other end (e.g., when adding additional B channels to the syst em), but do not want to lose all the D channel settings already completed (see caution below), a third state has been added to the D channels on the ACS-PRI/BRI card. The conf (configure) state is use d to initially configure the D channel and to change the configuration later.

When a D channel is in the configure state, it does not atte mpt to maintain a protocol se ssion with the far end. Als o, B channels assigned to a D channel t hat is i n the configur e state are reserved for the D channel, and thus are not availa ble to other D channels nor to oth er system modules (e.g. user ports or cross- connec t) th at mi ght want t o use them as DS0s. The only way to free up B channel s taken by a D channel in conf igu re state is to free each resource individually, or to put the D channel back into standby state.

The WAN setting shows the WAN link carrying thi s D cha nnel. In st andard a pplicati ons ( 23B + D), the WAN link will be the same as the WAN link carrying the B channels. In NFAS applications, this may not be the case.

The TS (timeslot) setting identifies the timeslo t on the WAN link that carries this D channel. Even though t he syst em a llows val ues t hat r ange f rom 1-24 for T1 links and 1-31 for E1 links, in almost all cases, TS 24 will be used for T1 applications and TS 16 will be used for E1 applications (when available).

4.4 Configuring ISDN Features

When one or more T1 WAN links terminating in a system are provi sioned f or ACS-PRI/B RI, users must configure the system’s ISDN features before calls can be set up.

Configuring ISDN feature s consist of the following four steps:

1. Assigning interface identifications to WAN link(s)

2. Assigning B channels to the D channel(s)

3. Coding the call-by-call service(s) to be used

4. Assigning call routing information

Each of these steps i s a ccessed f rom the to p level D ch annel co nfigurat ion s creen by sel ecting the corresponding menu item to brin g up the desired subscreen. Each subscreen is described in the following sections.

4.4.1 Assigning Interface Identifications

Each ISDN facility (interface) that terminates at the user’s premises is assigned a unique Intf. ID (interface identification) by the carrier. Whenever the system signals the carrier switch on

the D channel, it uses the Int f. ID(s) assigned by the carrier to tell the switch to which facility (interface) i t is referri n g.

Note: In the unlikely (but possi ble) event that a single facility is split between two carriers

(i.e., two D channels each controlling some of the B channels on that facility), it is possible that the same f acility (interface) will have t wo differ ent i nterface I Ds–one for each carrier. Thus, the list of inte rface I Ds is unique to a spe cifi c D channel only, but may be repeat ed across different D channels.

Figure 4-9 shows the Interfac e Identifi cation subscre en. This subs creen is accesse d by placing the cursor in the colu mn of the desired D chan nel , the n press i ng “i”. T he list of all inter faces (WANs) then appear with their assigned interface IDs. The default value is 99, which means “interface ID not ye t assi gne d .” Values for the Interface ID are 00-31 and 99.

You must assign an interf ace ID to any WAN link tha t wil l cont ain B channe ls before you will be able to assign the specific B channels to that facility.

4.4.2 Assigning B Channels

Choosing the “Bmap” option f rom the D channel configur ation screen of the ISDN card sc reen brings up the subscr een shown in Figure 4-10. This figure shows a typical “Bmap” scre en. It is a detailed map of all the WAN timeslots available to users as potential B channels.

When D channel #1 i s placed in the “ Configur e” mode, th e syste m reco gnizes the assign ment of WAN 1-1, timeslot #24 to this D channel and plac es it on the Bmap in the proper location. Notice that since all WAN links are T1 interfaces, the Bmap shows the last 7 places with a dash (-) indicating that the timeslot is unavailable for assignment.

Additionally, timeslots that are already in use by other resources (e.g. use r ports and cross-connect) are “blocked-out” with the letter “x” in the appropria te WAN timeslot. This letter “x” means that these timeslots are used as DS0s, and thus are not available for use as B channels. In Figure 4-10, tim eslots 14-19 on WAN 1-1 and timeslots 4-9 on WAN 1-2 are in use as DS0s and thus are unavailable for assignment.

4.4.3 Assigning B Channels to One D Channel

B channels are assigned to the highlighted D channel by placing the cursor in the row representing the WAN link (interface) and the column representing the timeslot. Pressing the “Enter” key will place a lowercase “b” in that time slot (the "Enter " key toggles the "b" off and on). This indicates that you have designated this timeslot as a B channel to be controlled by the highlighted D channel. You will not be able to place a “b” in any timeslot tha t is curre ntly occupied by a letter, number or dash, because these timeslots are controlled by other system modules, thus are unavailable to this D channel.

Figure 4-11 shows 36 B channels assigned to D channel #1. In this example, the carrier requested that yo u use tim eslots 1-9 on WAN 1-1, timesl ots 1 1- 19 on WAN 1-2, timeslot s 1-9 on WAN 2-1 and timeslots 1-9 on WAN 2-2.

4.4.4 Assignments for Two or Mo re D Channels

Previous paragraphs dealt with multipl e B channels for a single D channel. Often, the syst em will be called upon to manage the ISDN communicatio n for more than one D channel, as described earlier in this chapter.

In Figure 4-13, D channel #2 is changed from stdby to conf and is assigned to timesl ot #24 on WAN 1-2.

Figure 4-13. Assigning B Channels

When the Bmap selection is made (with D channel 2 highlighte d) , D channe l #2 appears on WAN 1-2, timeslot 24.

DS0s are still repre sented by “x”s. B channels whi ch have already been as signed to D channel #1 (and are therefore unavailable to D channel #2) are represented by “1”s.

Using the same procedure learned in the previous section, assign a lowercase "b" to eac h timeslot assigned by the car rier by pressing the “Enter” key in the column and row on the screen. In this example, timeslots #11-22 on WAN 2-1, #11-22 on WAN 2-2 and #1-24 on WAN 3-1 are assigned as B channels for D channel #2.

4.4.5 B Channel Status

Active B channe ls may ne ed to be ta ken out of se rvice peri odically for testing or m ainte nance by the user or the carrier. Choosing the “sTatus” option from the "Bmap" screen not only allows the user t o execute the se optio ns for individua l B channe ls on an act ive D channel, but also to review changes made by the carrier. Highlight the specific B channel and press the command option in the Menu of Actions to perform the desired action. Lower case letters signify changes made by the user; capitalized letters show carrier chang es.

In Figure 4-15, B Channels on time slots 6-7 on WAN 1-1 are placed in an Out of Service condition, and B channels on time slots 16-17 on WAN 1-2 are placed in maintenance mode by the user. B channels on time slots 8-9 on WAN 1-1 are in mai ntena nce mode by t he carrie r , and B channels on time slots 6-9 on WAN 2-2 are out of service by the carrier. Users and carriers can only reinstate B channels taken out of service or placed in maintenance mode by themselves.

4.4.6 Assigning ISDN Trunks

An ISDN trunk is a group of B channel s belonging to a single D channel. It consists of one or more B channels e ither contiguous or non-contiguous. All B channels in a trunk must belong to the same D channel. However, a trunk may be assigned across different WAN links when NFAS is used.

To access the Trunk Assignment screen, you must highlight the D channel on the Configuration scree n and press “B” to access the B channel screen. Pressing “N” from the Menu of Actions wil l bring up the Trunk Assignment sc reen. To assign a B channel t o a trunk group, place the cursor over the desired B channel and press the letter of the trunk group to which you want to assign this B channel. Capital letters between “A” and “O” are the only acceptable opt ions. Figure 4-16 shows a typical Bmap screen with four different D channels. T o simplify this discussion, al l four D channe ls have eight B channels.

Figure 4-16. Assigned T r unk Scr een

The first D channel on WAN1-1 has eight B channels. The first two B channels are assigned to Trunk Gro up “A.” The second D channel on W AN 1-2 a lso has eight B channels. B channels #5-6 are assigned to T runk Group “B.” The thir d D channel on WAN2-1 has eight B channels. B channels #7-8 are assigned to T runk Group “ C.” The fourth D channe l on WAN 2-2 also has eight B channels. B channels #1-2 are assigned to Trunk Group “D.” Once assigned to Trunk Groups, ISDN trunks can be placed in a routing table to show how to route incoming ISDN calls that need to be passed on to downstream equipment.

4.4.7 Routing ISDN Trunks

T o select a routing pattern for the ISDN trunks crea ted in the previous section, users must access the Trunk Routing screen from the Configuration sc reen. Pressing “T” f rom the Menu of Actions will bring up the Trunk Routing screen. To add a new trunk routing pattern, users must press “A” from the Menu of Actions, which will bring up the scre en shown as Figure 4-17.

Figure 4-17. Add Trunk Route Screen

The user should use the “right arrow” and “left arrow” keys to move the cursor through the eight sections (f our D c hannels and four tr unk s) of t he new trunk route . Pre ss the <Ent er> key to change each section. D channel numbers are changed with the “up arrow” and “down arrow” that sc roll through numbers 1-8 (the maximum n umber of D channe ls per system). The user changes trunk letters by typing a capital letter from A-to O (the fifteen available trunk letters per D channel).

All eight fields mus t be ch a nged for each new tru nk route . For instance, if you want a single incoming trun k group to be routed to three outgoing trunk groups on three different D channels, the process is easy. In Figure 4-18 the first trunk route sho ws this configuration. D channel #1, trunk group “A” is to be routed to D channel #2, trunk group “B.” If that route is busy, it will be routed to D channel #3, trunk group “C. ” If that route is busy, it will be routed to D channel #4, trunk group “D.” If that route is busy, the unit will drop the call.

ACS-PRI/BRI Card Configuring ISDN Features

Another example of this procedu re is shown in Figure 4-18. If you want a single incoming trunk group to be rout ed to only one outgoing trunk group, D channel #1, trunk group “A” is routed to D channel #2, trunk group “B.” The alternate routes 2-3 must contain the same information in alterna te route #2. Since this is the only alte rnative route, if tha t route is busy , the unit will drop the call.

4.4.8 Assignment of Services

Some carriers support cal l- by-call service selection in their ACS-PRI/BRI offerings. This feature allows us ers to sel ect a dif fer ent ser vice (and, us ually, a different billing rate) for each call placed.

If call-by-cal l service is supported, user s must tell the system which service(s) is/are suppo rted by each D channel, and what the code is for each service. The carrie r will supply a service code for each supported service. The Service format code is always two digits, a space and the name of the service. When placing a call using call profiles, only valid service codes will be allowed (see Call Profil es below fo r additional information about services).

If call-by-call service selection is not supported by the carrier or not required for the user’s applications, then there is no need to assign service to a D channel.

Figure 4-19 shows the Services scr een and the assignment of two mythical services (MASTERPIECE and BUSINESS PLAN) to D channel #1. The service codes of “01” and “02” were assigned by the carrier to these services. Remember to Save your work before returning to the top level D channel co nfiguration screen.

4.4.9 Routing of Incoming Calls

Call routing in the system is described in the introduc tion section of this chapte r. Assignment of phone numbers for routing calls between D channels is done from the routing subscreen.

Figure 4-20 shows the ISDN routing subscr een. It is accessed from the D channel configuration screen by pressing “o” (lowercase letter o).

Figure 4-20. Routing Numbers Screen

Each D channel may be assigned two ten-digit phone numbers to be used for r outing calls addressed to those phone numbers. The use of the wild card letter “x” means any digit will match. Note that D channel r outing occur s only aft er all atte mpts to route a call to an HSU port are unsuccessful.

If local routing is disabled (Rout e Local = no), any c all coming into the system on a network side (i.e., local) D channel will be routed only to a user side D channel based on the called number. Even if the called number matches, such a call will never be routed to an HSU port or a network side D channel when local routing is disabl ed.

The routing table should alway s contain the default number "xxxxxxxxxx" (10 Xs) to make sure that all dialed numbers are routed to the network.

Configuring ISDN Features ACS-PRI/BRI Card

If local routing is enabled (Route Local = yes), then any call coming i n on a D c hannel will be routed to the f irst matching phone numbe r, regardless of whether or not the match i s for a local device.

Any calls originating from an HSU port will be routed to the D channel specified in the call profile, regardless of the called number.

Model No.

4.4.10 Special Numbers

Pressing L from the Menu of Actions will bring up the Speci al Numbers sc reen shown in Figure 4-21. Special numbers are any telephone numbers that the use r does not want routed to HSU cards. Special numbers have the highest priority in the number searching process. Any number that matches one of the special numbers wil l always be routed to the default trunk "xxxxxxxxxx," to the ISDN network and then into the Public Switched Network.

Some special numbers used in the United States include "0," "00," "911," "411" and "611." Some special numbers used in the foreign count ries includes "0," "1 19" and "110." The special number table can contain te lephone number s up to 10 digits in lengt h. It also inc ludes the use of the "+" character, so that the special number "0+" would include any series of numbers that starts with the number "0." The ch aracter "x" is u sed as a wildcard in the same way as the routing table.
