    Field Description
    Modem 
    ConnectionDefault is none
     for Release 8 SCC. Set to external
     if a modem is used.
    Modem Name
    This field  is 20 c harac ters long  and  p ermits alp hanumeric  c harac ters to 
    p rovid e a uniq ue q ualifier for a given mod em.
    RTS/CTS 
    EnabledInforms mod em that c ommunic ation with the d ata sourc e UART is d riven 
    with RTS/CTS flow c ontrol. The d efault 6-c harac ter field name is &H1
    . 
    Set the field  name to \Q3 for Intel mod ems. This field  is not 
    c ase-sensitive.
    Asynchronous 
    Data ModeConfig ures mod em as an async hronous d evic e. This 8-c harac ter field  
    name has a d efault value of &M0
     (d efault) for Release 8 SCC. Set the 
    field  to &M0&Q0 for Intel modems. This field  is not c ase-sensitive. 
    DTE 
    Auto-Data 
    SpeedAd justs the sp eed  of the d ata sourc e (DTE) UART to the outg oing  
    (mod em-to-mod em) d ata rate. At maximum, this sp eed is 9600 b aud . It 
    is not d esirab le to have the serial d ata fill the mod em buffer faster than 
    the outg oing  data rate, sinc e d ata c omp ression is d isab led . The field  
    name has a 6-c harac ter b lank d efault value. The Parad yne produc ts use 
    S90= 1 to enab le this func tionality while the Intel p rod uc t uses \J1 to 
    enab le similar func tionality. This field  is not c ase-sensitive. 
    Disable Data 
    CompressionTurns off the d efault d ata c ompression alg orithms used  b y most 
    mod ems. The field has a b lank field  of 6 c harac ters as d efault. The AT 
    c ommand s that c ontrol this are supp orted  b y similar c ommand s; 
    however, these c ommand s d o not op erate in the same manner. The Intel 
    modems require H0%C0 to disable V.42bis & MNP Class 5 data 
    c omp ression alg orithms. The Parad yne p rod uc ts only use %C0 to 
    d isab le b oth algorithms. This field  is not c ase-sensitive.
    Enable Error 
    ControlTurns on the V.42 LAPM and  MNP error c ontrol p rotoc ols. The field has a 
    b lank d efault of 6 c harac ters. The Parad yne p rod uc ts use the c ommand  
    \N5 to enab le V.42/MNP/Buffer error c ontrol while the Intel p roduc t uses 
    \N3 to p rovid e similar func tionality. 
    Misc. Init. 
    ParamThis field  has a 20-c harac ter b lank d efault and  sup ports any initialization 
    p arameters not alread y sp ec ified . The AT c ommand s sp ec ified  in this 
    field  are always the last initialization p arameters to b e sent to the 
    external mod em. This field  is not c ase-sensitive. 
    Auto-Answer 
    Ring NumberThis field  c ontrols the number of ring s required  b efore the mod em 
    answers an inc oming  c all. This field  should  b e set to S0= 10.

    Add Circuit Packs
    When installing additional features or equipment, it may be necessary to install 
    ad d itional port c irc uit p ac ks. See Tab le 5-24
     for a list of c irc uit p ac ks. This is a 
    g eneral p roc ed ure to use when ad d ing features or eq uipment that req uire ad d ing  
    circuit packs.
    !CAUTION:
    The control circuit packs with white lab els cannot be removed  or installed  
    when the power is on. The p ort c irc uit pac ks with g ray lab els (older version 
    circuit packs had purple labels) can be removed or installed when the 
    p ower is on.
    1. Log  onto the system and  answer y
     to the Sup p ress Alarm Orig ination 
    q uestion d uring  log in.
    2. Install the c irc uit p ac k into the c arrier. Dial Type
    This field  c ontrols the typ e of interreg ister sig naling  used  b etween the 
    mod em and  the CO. This 3-c harac ter field  is d enoted  b y “ T”  for tone 
    dialing (default) and “P” for pulse dialing. This setting depends on type 
    of line (tone or p ulse) to the mod em.
    Adjustable 
    Make/Break 
    RatioThis field  c ontrols the make/b reak ratios of p ulses and  DTMF d ialing . 
    Most mod ems have sup p ort for d ifferent make/ b reak op tions for p ulse 
    d ialing  only. Parad yne, Intel, and  U.S. Rob otic s use the d efault &P0
     to 
    selec t a ratio of 39% make and  61% break for c ommunic ation for the 
    United  States and  Canad a. The op tion &P1 sets a ratio of 33% make and 
    67% break for the United Kingdom and Hong Kong. This is a 
    5-c harac ter b lank field  (d efault) and  is not c ase-sensitive. 
    Dial Command
    This field  has a d efault of “ D”  in a 3-c harac ter field . This field  d enotes the 
    stand ard  d ialing  c ommand  of the mod em and  is not c ase-sensitive. 
    No Answer 
    Time-OutMost mod ems provide a timer that ab andons any outb ound  d ata c all 
    after a p red etermined  interval. This is a non-ad ministrab le parameter.

    The TN799 Control LAN (CLAN) p ac ket p ort c irc uit p ac k p rovid es TCP/IP 
    c onnec tion to ad junc ts app lic ations suc h as CMS, Intuity, and  DCS Networking . 
    The CLAN c irc uit pac k has 1 10b aseT Ethernet c onnec tion and  up  to 16 DS0 
    p hysic al interfac es for PPP c onnec tions. In add ition to the TCP/IP func tionality, 
    CLAN extends the ISDN capabilities for csi models by providing Packet bus 
    ac c ess.

    The CLAN TN799 c irc uit p ac k c omb ines the func tions of the PGATE and  PI c irc uit 
    p ac ks into one c irc uit p ac k. The PGATE or PI c an b e used  with the CLAN to 
    c reate an X.25-to-TCP/IP b rid g e for ad junc t and  DCS c onnec tivity.
    The d ata link interfac e (b etween the proc essor and  the p hysic al sig naling  link) is 
    p rovid ed by (or through) the TN799 C-LAN c irc uit pac k. In some c onfig urations, 
    the TN799 p asses the sig naling  information over a sep arate 10BaseT TCP/IP 
    network (usually via a hub ). For use with 10BaseT, c onnec t the ap p rop riate p ins 
    of the I/O field  to the hub . For p inouts and  d iagrams, refer to the end  of this 
    c hap ter. In other c onfig urations, the TN799 c irc uit p ac k c arries sig naling over 
    p oint-to-p oint p rotoc ol (PPP) for sub seq uent inc lusion (via the switc hing fab ric ) in 
    the same DS1 b it stream as the DSC voic e transmissions.
    As an op tion to the TN768 Tone-Cloc k, a TN780 Tone-Cloc k c irc uit p ac k (installed  
    in the PPN) c an interfac e external Stratum 3 sync hronization for DS1 
    c onnec tions.

    A DS1 c irc uit p ac k is required  for p oint-to-p oint p rotoc ol (PPP) c onnec tions. A 
    TN799 C-LAN c irc uit p ac k is req uired .
    1. Determine the p ort assig nments of the c irc uit p ac ks to b e ad d ed . If there 
    are no availab le p ort slots in the p roc essor c ab inet for the C-LAN c irc uit 
    p ac k, p lac e it in a R8 EPN c ab inet p ort slot. You d o not need  to p ower 
    d own the c ab inet to install the c irc uit p ac k.
