# rev history
# -------------------------------------------------------------------------------
# 0.0.1 - initial release
# 0.0.2 - 2008-12-11 Th; implement requirement that first SMG interface 
#         activated is a TDM_VOICE_API;
#         this means that if ss7boxd is running then the first wanpipe started by
#         ss7boxd must first activate a TDM_VOICE_API interface; this interface must
#         be either real or an unused dummy; if ss7boxd is not running then the first
#         SMG wanpipe will activate a TDM_VOICE_API interface by default so nothing
#         is needed in this program in this case; implementing this requirement means
#         that ss7box config information is needed before making the wanpipe conf files,
#         there will be a change in the order of tasks in this program: first collect
#         info then build conf files
# 0.0.3 - 2009-01-21; changed ss7boost.conf default hearbeat rate to 5.00 sec;
#         wXgY interface names for xmtp2 links must have Y==active channel; this means 
#         the voice wXgY name will have a Y value that is not an SS7 link channel
# 0.0.4 - 2009-01-21; extended wXgY concept to ss7boost.conf TRUNK section
# 0.1.4 - 2009-04-07 Tu; major re-work; reformatted the configuration spreadsheet to eliminate 
#         redundant entry of information, and to prepare to explict span/chan to
#         CIC/trunk-group assignment; allow for more than 1 ss7 link per span
# 0.1.5 - 2009-05-10 Su; added TDMV_DCHAN and TDMV_HW_DTMF to wanpipe configurations
# 0.2.0 - 2009-05-27 We; changed inbound routing sections in ss7box.conf to support
#         isup and sccp in separate sections
# 0.3.0 - 2009-06-18 Th; change ss7boost.conf to sangoma_isupd.conf; create the 
#         tgX_isup_timer.conf files
# 0.3.1 - 2009-07-01 We; change SS7BOX section of sangoma_isup.conf to allow two
#         ss7box connections
# 0.4.0 - 2009-08-26 We; add conf file revision field to ss7box.conf and sangoma_isup.conf
# 0.4.1 - 2009-09-24 We; add numeric_sort to support lists of t/g and trunks with more than
#         10 entries
# 0.4.2 - 2009-09-25 Th; changed numeric_sort to lamba; changed tg-trk list building
#         to support t/g and trunk list with >10 entries
# 0.4.3 - 2009-10-27 We: added support for creating wanrouter.rc file
# 0.5.0 - 2009-11-07 Sa: added support for PCR/Basic MTP2 error correction option
# 0.6.0 - 2009-11-13 Fr: added routing protocol field to outbound routes table in ss7box section
# 0.7.0 - 2009-11-18 We: same format at 0.6.0; adds the TG_CIC_SPAN_CHAN_ASSOC table to
#         sangoma_isup.conf
# 0.7.1 - 2009-11-19 Th: voice channel dictionary; changed span from TDMV version to 
#         isupd version (TDMV span == isup span + 1)
# 0.8.0 - 2009-11-25 We: fix range comparisons in voice channel mapping function; 
#         add option to the ss7boost trunk group table entry to control assigning a CIC to 
#         non-voice channels
# 0.8.1 - 2009-11-30 Mo: fix index for non-voice channel test in the code section that
#	  makes the voice channel map expressions prior to building the wanpipeX.conf 
#	  files
# 0.8.2 - 2009-12-10 Th: changed the ACTIVE_CH field in wanpipeX.conf so that it is independent of
#         ISUP layer.  added TE_RX_SLEVEL and TE_SIG_MODE to wanpipeX.conf
# 0.8.3 - 2009-12-10 Th: TE_RX_SLEVEL coded to 12db rather then stock 30db to prevent bouncing alarms
#	  when port is not connected
# 0.8.4 - 2009-12-16 We: fix index for test of alternate route in outb_route list
#         when writing ss7box.conf
# 0.8.5 - 2010-01-19 Tu: fix map_voice_channels for-loop initialization to handle
#         ranges starting at 2..n
# 0.8.6 - 2010-01-31 Su: fix in .fr; adapt 0.8.5 for not assigning CIC to non-voice chans

# TODO list
# 1. HW echo control option
# 2. individual span/chan assignment of CIC and t-g
# 3. open and read existing /etc/wanpipe/wanrouter.rc and add those wanpipes to
#    wannrouter.rc created here
# 4. change ss7boost references to isupd
# 5. change inb isup and inb sccp to m3ua_isup and m3ua_sccp because those tables
#    are now used for inb and outb m3ua routing
# 6. add control in PORTS section to allow specific channels to be included in the 
#    voice channel ACTIVE_CH map in wanpipeX.conf; this is for the special project
